Hi, I was having a weird problem with a certain type of files freezing up a folder, they were video files and I used CCleaner to clean everything that was outdated. This didn't solve the problem, although updating some codec files did (for the most part, one video file still won't play for some reason).
Since then I had a program try to auto-update (U2BViews Viewer), and it stopped working. So I tried to re-install it and ever since then I get the:
"This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package."
error when trying to install the program's Setup.msi file. I've tried all different things to fix it and nothing seems to work. I've noticed that this problem started AFTER using CCleaner to clean several registry entries.
I'm thinking that CCleaner deleted something needed to open and run msi files. Should I use the first registry backup or will that screw up the previous video issue, or is there something else that I can do?

To me it sounds like a corrupt setup file. Re-download it again and see if that can fix the issue.
If you're still having issues perhaps reinstalling Windows Installer from Microsoft may help.
I would try a couple of things:
- Try a repair with your Windows installation disk.
That's jumping the gun since the "repair" will wipe out everything to re-install Windows. I'd think that would be last ditch effort advice.

The "Repair my installation" option on the Windows Vista and Windows 7 install CD does not delete any data. The last time I ran it was about six hours ago*. I can confirm that my data is exactly where I left it.
Sounds to me like there were issues before ccleaner was used as The WebAtom pointed out. Codecs can cause all sorts of weird problems.
I would give Andavari's suggestions a go first, then if everything is still not working perhaps do a repair install, this doesn't usually lose user files like it used to on XP but should still be used only as a last resort, and only if you have a Windows 7 full install disc which matches your system (eg 64bit)
Usually if more than one is installed at once, and if installing a new version over an old version. With codec packs it's best to always do clean installs of them.
