Hi, Thanks for a fast responds.
I deleted the folder but when I installed a microsoft office it gave me an error. "ERROR 1317. Setup cannot create the folder c:\Program files\common files\microsoft shared\EQUATION. verify that the path exists in your system and that you have sufficient permission to update it."
The folder exists but I'm not able to open it. When I try to open the folder it tells me "the disk is not formatted. Do you want to format now?"
