Hello, I'm running Windows 7 Ultimate 64 bit. I cannot install some programs that have to beusing setup.exe (if I use msi installer - it's OK, but some programs like Adobe Photoshop Elements must be installed using setup.exe). When I click on setup.exe, I'm instantly getting a message that this file cannot be found. This is not a problem with the particular program, but with many. Also, couple months ago I didn't have these problems with the same programs. I've tried Microsoft FixIt - didn't help. I don't know when this happened, but at least two months ago, so I cannot even use the restore point. I'd also ran SFC /scannow, it fixed some problems, but not this one. What could be wrong here? Are there any ways to fix this besided re-installing Windows? Thank you.
