Hi, Thanks for the post! Why you run this command? Did you encounter some issue? Maybe you needn’t run this. If you really want to register this file, please make sure it’s compatible with Windows 7. In addition, what is the version of you Windows? 32-bit or 64-bit? Since you use regsvr32 to register the actskn43.ocx, you should make sure your windows is also 32-bit. If not, you need the following steps to register the actskn43.ocx: Run cmd as administrator, then input: cd \windows\syswow64 regsvr32 c:\filename.dll Hope it helps!

Hi, I have exactly the same error on windows 7 and your "fix" doesn't solve the problem. Cheers Danny

Hi, I had the problem under Windows XP Home Edition. Using: C:/Windows/systems32/regsvr32.exe From the Command Prompt (CMD.exe): regsvr32 "C:\Program Files\SomeApplicDir\MyOcx.ocx" The message indicated the following: DllRegisterServer returned 0x80040201 (which seems to be a security issue as indicated here above and also in other forums) I used www.DependencyWalker.com to detect some missing files for regsvr32.exe: EFSADU.DLL IESHIMS.DLL WER.DLL I found lots of confusing information on forums telling you to somehow install these files or restore them, but that doesn't make sence. I even tried SFX /SCANNOW from the command prompt, which restores missing Window System Files (which can't hurt if you ask me), but even that indicated those files weren't supposed to be there, because they were not there after it completed (It took a long while for it to process and I didn't see it finishing by the way). But only on one forum, some Microsoft Moderator indicated that these missing dll's are not of importance for Windows XP, so I searched further and came back here. Nothing helped. Then I tried as follows: I created a short cut pointing to the "C:/Windows/systems32/CMD.exe" on my Desktop, then right clicked it, then clicked on run (or execute (I have a dutch XP version... so I'm nut sure what's the English text) ) as Administrator... Then the one important thing that made it work: UNCHECK the checkbox that protects you from unwanted changes to your system. Being at the command prompt now, type the following: regsvr32 "C:\Program Files\SomeApplicDir\MyOcx.ocx" ==> This registers the activeX control regsvr32 /u "C:\Program Files\SomeApplicDir\MyOcx.ocx" ==> This should unregister the activeX control It worked for me, my *.ocx were registered successfully. (I didn't try to unregister them though, but I merely want to indicate the procedure is similar). Good luck, Kenneth
