The procedure entry point apsGetInterfaceCount could not be located in the dynamic link library wlanapi.dll
Okay so today ive installed the new Windows Serivce Pack 3 and then after reboot i noticed i do not have internet workng and i see such errors:
and
The procedure entry point apsInitialize could not be located in the dynamic link library wlanapi.dll
The solution is hopefully preety easy but not easy to find on forums because people write there a lot of not usefull things. Of course Glowicki blogging tips gives best and easiest solution as usual so Yopur D-link adapter will work properly under Windows.
1. It doesnt matter which D-link adapter You use. Dont waste time seeking for new drivers either.
2. Download this file which is pre SP3 driver compatible with all D-Link versions. It is a wlanapi.dll wlanapi.dll to fix Service Pack 3 D-Link problems
3. Go to directory of system32 in Windows and check version of wlanpi.dll now open in it notepad and modify this lines:
%&()XM)@var WIndows…. naa just kidding.. solution is way easier. It is just funny to read what people write on this forums. I even saw solutions of uninstalling whole Windows Serivce Pack 3. Anyways skip this point.
4. Copy the downloaded of Glowicki Problogger site wlan.dll to this folders:
- ProgramFiles\D-Link\AirPlus G
- ProgramFiles\ANI\ANIWZCS
5. Restart computer and enjoy internet like before.
If i helped anyone would be nice if You holla in comments as usual!



Thanks for the wlanapi.dll fix after XP SP3 – a simple, elegant and effective way around the problem. Great stuff.
Thanks for the wlanapi.dll fix after XP SP3
thankyou for your straight forward steps. this only got rid of the apsInitialize error message for me.
Do you have an idea how to get rid of the other one, apsGetInterface?
You are my Master!!
it works!!
Thank you so much for the quick easy fix!!
Thanks a lot ! Your explanation was very effective !
It works! Slick & simple, ‘cept for the notepad edit part
Although people may find it beneficial to hold the “Any” key while copying the dll. While it doesn’t really help, unlike a Windows update, it’s mostly harmless!
Many Thanx!
Thanks, it seemed all ok when suddenly a blue screen appeared wiht the following error:
DRIVER _IRQ_NOT_LESS_OR_EQUAL
By the way, the folder to copy the downloaded file, in my computer is called:
- ProgramFiles\ANI\ANIWZCS2 service (I wonder if it could affect or not)
Elute what system are You running? This is a bit strange because dirs should be named like i said. I suggest reinstalling D-link with newest drivers and then using the method here. Its 100% working!
thank you very much
it works now
Thx a lot man
Thanks, this worked great. I have DWL-G630 Rev D card and D-Link site only has updated Rev E drivers, so this saved me from a lot of aggravation. By the way, weird directory names were in this version of D-Link as well. The folders I stored your dll into were:
- ProgramFiles\D-Link\AirPlus G
- ProgramFiles\ANI\ANIO Service
- ProgramFiles\ANI\ANIWZCS2 Service
Everything working OK so far.
[...] of forums, I found there was a very quick and easy solution to the error messages at this site: The procedure entry point apsGetInterfaceCount could not be located in the dynamic link library wlan… It solved the problem, but it’s suspiciously straightforward. I guess I’ll have to wait and see if [...]
Damn! pretty cool solution, n yea a lot better and easier then the other forums
tnx for sharing
Such an easy copy paste solution to an error i’ve been putting up with for months now. grrrr wish I had checked out your site first instead of all the others that didn’t work.
I’ll be checking here first next time.
Thanks
Thank you a lot ! I was almost 3 months annoyed by this dammit error message. Now it works pretty fine!
Fabiano
Finally that stupid error message is gone! Thank you for the quick fix.
Many thanks for the quick and easy fix man!
Both messages are gone.
It’s so hard to find good solutions.
As we say in french “chapeau bas Monsieur!” which means approx “I take my hat off when I see what you’re able to do”.
Thanks alos to Kwizzler for the “othe directory names” thing.
So long

Hey thanks for the help worked great except im still getting the apsInitialize pop-up do you have any idea’s at how to fix it…cause that would be great
D-Link Air G520 with 3 months of 2 error messages (ANIWZCS2 & WLANAPI.DLL) without connection. Ready to formatt thinking on some virus or trojan or missing file windows, tried with new updated driver but couldn’t get off those annoying error messages,googled the errors on last try, & find yours among many others more complex. Yours solution very easy and useful. Only problem need always installing drivers and file without hardware PCI wireless adapter, unpluged. I’ve got connected again! without having to formatt and reinstall new XP and else! Thanks!!!
Worked, thanks for sharing!
Just like to say thanks for your help in resolving this error. It was solved in a matter of moments.
Thnaks a lot ! , btw its cool i dont have to register to put a comment.
Thanks for that very useful topic.
you are a master!!!!!!
it worked perfect
Thanks, worked for me too.
It worked. At startup, I was getting entry not found in wlanapi for both apsGetInterfaceCount (from AirGCFG.exe) and apsInitialize (from WZCSLDR2.exe). I stored your dll into:
- ProgramFiles\D-Link\AirPlus G
- ProgramFiles\ANI\ANIWZCS2 Service
But not in
- ProgramFiles\ANI\ANIO Service.
and both “entry point not located in wlanapi” messages stopped showing up thereafter. Thanks.
You’re DA MAN!!!!!!!!!!!!!! I worship at your feet!!! You can’t see me now but I am bowing to your website.
Happy to hear the post helps. I made a good deed, hope karma will give me some cash back haha.
Thanks, had to add the new drivers to get it recognised, but works a treat
You save me.
Thank you very much!
I was hoping that my problem with apsGetInterfaceCount (from AirGCFG.exe) and apsInitialize (from WZCSLDR2.exe) would be solved, but they aren’t. I did all you wrote in your instructions but the anoying message still appears on my desktop. And I still don’t know why.
great work… you got rid of those two really annoying (goes into sound effect mode)…”DOONK”s, with their annoying messages for me.
I am drinking a beer to toast you right now !
Thanks! You da man.
Hey Bro, sorry but can it be that you would have to change the files extention? I mean i have downloaded an *.exe file and not an *.dll would be really nice to know…
But hey thanks for this anyway nice to see that it worked for so much already.
Greetings
hey
sorry was an opera problem so if you download the file do it with any other browser!
Greatings
Dear Friend,
Your help was just so fantastic — so very good. For months and months I would get the following messages on my computer screen when starting up: “AirGCFG.exe – Entry Point Not Found” and “WZCSLDR2.exe – Entry Point Not Found” I didn’t know what to do! I was just stuck. Well, yesterday I stumbled onto your wonderful Website — and now the problem has been solved!!! I am so grateful for your kind advice and your going to the trouble of sharing it with the public. May God bless your service to people. Alex and Eva Peck (writing from Brisbane, Australia)
Thanks for that — it’s been nagging me for months. Tried Microsoft, but after being on hold for ages, the line dropped out when the tech came on the phone.
No more WZCSLDR2.exe – Entry Point Not Found message because of SP3 crunching up the D-Link DLL!
jjj
Good, quick, easy solution. Many thanks.
Cannot open link: wlanapi.dll to fix Service Pack 3 D-Link problems. Can you pls assist. I’m desperateley trying to solve this problem, which has been driving my crazy ever since my SP3 installation
Man, you made my day. It worked perfectly and all my headaches are gone. Thanks a million
Thanks! Finally fixed the annoying error everytime I booted up. Simple and quick!
Well done, mind you I did go looking for taht file in System32, nearly got me, well done!!!
Hey
Just one prob, I dont have those listed Directories even though I get the same errors. The Directories i have are :
C:\Program Files\ANI\ANIO Service
C:\Program Files\ANI\ANIWZCS2 Service
C:\Program Files\D-Link\AirPlus XtremeG
Where do I copy that dll now ?
Awesome! You are the master, no more “The procedure entry point apsGetInterfaceCount could not be located in the dynamic link library wlanapi.dll” flashing up every time I reboot. Thanks!
Thanks for this – after half a day lost, the Service Provider & IT company not able to help – and three daughters screeming at me that their networks are down and they need to study – its fixed – A BIG THANKYOU. And it works if you save it to a USB and then just upload it into the affected computer/s.
Many thanks. Has very quickly solve the problem that has been driving me nuts for the last few months. Again, many thanks.

I was experiencing the same thing on my system. I am running Windows 7. Figured even though fix was designed for earlier version operating system I would try procedure and see what happens. I worked perfect!
I did notice on mine for the file location ProgramFiles\ANI\ANIWZCS mine was ProgramFiles\ANI\ANIWZCS2 it had a 2 added to the end. Still worked great on Windows 7 operation system.
Thank you for this fix,
Dman
Great! Thank you very much for sharing
Damn, Thant was the easiest “bugfix” i ever found on the web!! Thanx!
I’ve been looking for this EASIEST WAY SOUTION for like 2 days , all of the solutions I found was sooooooooo loooong ! haha..
ur such a genius person !;)
I bookmark your site already..
Thanx for the info. The 1st part did not work for me because there was no ProgramFiles\D-Link\AirPlus G. The 2nd part worked great! I did fix the 1st part however by replacing it with the NetProp.dll file. No more errors and everything is working fine.
Could you please xplain what to do after copying to notepad and modify this line? : %&()XM)@var WIndows
Reason being my computer crashed in the process and now I don’t now what to do??????
Nah only kidding LoL
Your fix worked a treat.
Thanks a million

Great! Worked no issues but after opening the dll with notepad I had to reinstall my Windows…
That was funny…
Thanks so much for your solution to the problem with the D-Link Adapter. It sure was the easiest and fastest solution. You sure know what you are doing, which is more than I can say from other entries on some forums.
Thanks much
Great fix. Thanks.
Have been looking for a solution for a long time (restore point, update drivers…) Thks for a simple and effective solution. Worked like a charm…
You are the best this was driving me crazy. Thank you thank you thank you.
Awesome fix – the errors went away. Similar to an above comment, the ANI directory I copied the wlanapi.dll to was
C:\Program Files\ANI\ANIWZCS2 Service
Thanks again.
YEE-Haaw…simple,quick and easy. i copied the wlanapi.dll to ‘C:\Program Files\ANI\ANIWZCS2 Service’ on my computer as well.works like a charm.thank a billion
it worked! thank you! i did NOT want to call my friendly neighborhood IT guy.
you are awesome!
Thanks for the easy steps to resolving this issue, which has plagued so many of us, who have taken the opportunity to upgrade to ‘Service Pack 3,’ good looking out man!
The first one disapp, working on the second… Thanks
This was information to eliminate the error message was absolutely spot on. I wasted money on All-in-One PC Tune-Up – fortunately I got a huge rebate. I’ve put in at least twelve hours trying different fixes with no success. I’d buy you a beer but the PayPal was in a foreign language that I couldn’t be comfortable using.
Thanks a million!
oh thanx for info i didnt know the button was in other language. now its fixed an u see english there from start.
im happy i helped u all and im really happy some of u actually bought me a beer
thats not much for life saving right?
I’m afraid I may have been overzealous in my praise. Today when I log onto mt computer none of my start icons or tool bar show – no task are running, and nothing happens when I right click on the desktop.
What do you think happened?
this is for 100% not connected to d-link issue – if the tip wouldnt work in worst case u would still not have internet.
i assume while ‘trying to fix’ before finding my site u must have changed some setups [maybe turned off firewall or windows updates] and now when u got internet back something other failed.
try uninstalling All-in-One PC Tune-Up and fixing what it did
I delayed install of Service Pack 3 due to the errors that were coming up but they are now gone thanks to the work you have done on this blog. Thanks very much, Craig (Brisbane, Australia).
hallo ,
thanks a million and for people like you, think you should charge Mr. Bill Gates for fixing his errors!!!\vista must have cost the world millions let alone all the blue screens, and they seem to be back and build into win7, with wasted time world wide. it is a disaster..
Anycase thanks
thys
I don’t have either of the files i am supposed to put the dll file in.
Mine are:
ANI\ANIO Service
ANI\ANIWZCS2 Service
D-Link\Wireless G WUA-1340
Any other ideas?
Thanks
Thanks for the info on wlanapi.dll Your fix did the job. Not a big issue, just annoying on start up.
