I assume that you're talking of a file install.log in a programme folder. If that's the case, reboot, open Winddows Explorer, and delete the folder, that should remove the file as well, rebooting afterwards. You reboot before to shut down any programme using that file! Also, check for spyware or malaware.
When I try to remove a program I get "Could not open
install.log File" does anyone know how i can remove it ?
