Can't Open Certain .EXE Files In Windows 7

I do have a valid product code. But I don't have an installation disc.

Unfortunately, yes. You can backup your data first, but there is no point in trying to back up such a damaged system.

Can't you download the Installation?

Well now I'm in deep trouble because I followed the instructions to this (How to Fix a Corrupted Windows Installer | eHow.com) and now I don't have msi.dll and other files.

Stupidly forgot to backup.

Anyone can help me on getting it back!?

Those instructions told you how to rename the files in question. To get them back, just rename them back using the same procedure, just remove "old" from filenames.

Also check out what Microsoft has to say about corrupt Installer now.

the same problem with me befor two hours and i found the solutionbefore 2 minutes..

if you read the error message you will see it talking about the name of the label and the directory name
just try to move the EXE file you want to run to the desktop...it will run.

the reason is the Directory and the folders name... it doesn't accept \\ \\ / [ ] : | < > + ; = . ? "

see this article:

it seems there is a few more little problems i will fix it and publish the solution.
