I am using Windows 8.1 Pro 64-bit.
I see this error, almost every time I launch an executable file (to install it) but not for all of them. I don't see the error when I use Run as Administrator.
I looked around, and found a solution: I needed to give permissions to the current user for the temp file as shown in the picture below:
The problem here is solved temporarily, but it goes back to give me the same problem after restarting the PC.
What can I do to prevent such a thing? I don't really want to use the built in Administrator account all the time.
