Last August 26 of 2011 I was trying to install IE 7 Standalone on my PC(Windows 7) to test my web project for cross browser scripting then suddenly my pc is throwing an error message (No such interface supported).
All I thought my pc have been infected by a virus/malware so I installed trojan remover, anti-malware, etc....
But still haven't solve anything. :(
And this morning I came up with a simple solution provided by GOOGLE :).
1.) Go to Start > Run, and type in 'cmd' to open Command Prompt.
2.) type: FOR /R C:\ %G IN (*.dll) DO "%systemroot%\system32\regsvr32.exe" /s "%G" and then hit enter.
That's all! you just have to wait for the system to complete re-registration of all DLLs.
Expect a lot of error dialog messages to pop-up. Don't worry, just ignore and close all pop-up error messages.
