Error “No such interface supported” when Accessing Personalize Context Menu Option in Windows 7

When you right-click on the Desktop and choose Personalize, the error "No such interface supported" is shown and the Personalize window doesn’t load.

Registering the file actxprxy.dll resolves the problem. To do so, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

Type the following command and press {ENTER}



"%SystemRoot%\System32\regsvr32.exe" "%SystemRoot%\System32\actxprxy.dll"

If you have Windows 7 64-bit Edition, run this command.

"%SystemRoot%\SysWOW64\regsvr32.exe" "%SystemRoot%\SysWOW64\actxprxy.dll"

You should be able to access the Personalize applet now!
