Hi I am getting the operation cannot be completed error when i tried to open Visual st开发者_开发技巧udio 2010. Previous to that I was trying to install web platform and didnt install but that is all I did...anyone have suggestions...i tried restart my pc...

Try devenv /setup, devenv /resetsettings, or devenv /resetuserdata. Important: only try the last two as a last resort since they will reset your settings.

Assuming you're on a 32-bit OS, devenv is available from the command-line at \Program Files\Microsoft Visual Studio 10.0\Common7\IDE or from the VS command prompt.
