"ClassFactory cannot supply requested class" error with windows 7 and IE10.


When you click on a .html file in Windows Explorer on Windows 7, and get this error:

"ClassFactory cannot supply requested class"



Another software installation may be currupting or registering old version of ieproxy.dll. You could try Re-registering this ieproxy.dll again to see whether problem goes away.

To re-register follow the below steps.

1. Login to System as Administrator.
2. Go to command prompt.
3. Navigate to C:\Program Files\Internet Explorer for 32 bit.
4. Type regsvr32 ieproxy.dll and press Enter. It will register the ieproxy.dll with this confirmation:




5. Type regsvr32 actxprxy.dll. (Some times this dll also may get affected by some other application...Note: if this dll file is not in your IE folder it could be in C:\Windows\System32).
Again you get this confirmation:

6.  Restart the system.



If the problem persists, consider resetting Internet Explorer to its default configuration:
