Hi Once a program is installed in W 2

Hi Once a program is installed in Windows XP if I accidentally try to reinstall it again under another user’s name, it will not work at all and it doesn’t let me uninstalled or reinstall it.

Thanks.

So what's the question? (and the program?)

Hi the question is how can I uninstall the program completely so I can install it again? I tried to clean up the registry manually and it didn't work. I used Registry Vacuum Cleaner in anther machine and it didn't work. This is happening with any program that is accidentally reinstalled in any machine. The reinstallation will stop near the end and the program will not run.

you mean you can't uninstall ANY program (that you've installed twice)? Even logged on as Administrator?

Can you install them again (logged on as Administrator), then uninstall them?

Why are you installing programs twice?

What did your 'manual clean-up' consist of?

If you are manually trying to remove a failed installation it would assist you if you got assistance from the program's support section. This way you would know the names and locations of the registry keys, files and folders to remove.

Anything you have installed very recently could be removed by using system restore to revert back to before installation.

In Add or Remove, very often there is the option to repair an installation, before you actually uninstall it.

You could also try using Safe Mode and the built-in Administrator to perform your tasks.

I vote with linney on this.

Many registry entries are made that are not "plain text", they can involve GUID references and you will be very unlikely to find them on your own.

Daemon Tools, a great utility, gave me fits in one release where I could not go backwards to uninstall it, or forwards to upgrade it. The answer was a GUID entry in HKEY_CLASSES_ROOT, and only the Daemon website offered the key value to repair the installation.
