I installed unknown programm, and i can not uninstal it by windows installer, and if i use CCleaner tool "Delete entry" have error like: "Cannot delete MSI installer". How can i delete this programm?
If the uninstaller is not available from Control Panel/Add-Remove then you will have to do it manually. It is not as hard as it appears. All you need to do is delete ALL of the folders tht were created for the program. Then you can run CCleaner to help get rid of the Registry entries. If that is not enough-then you will need to edit the Registry.
WARNING_Editing the Registry is Dangerous! Make a backup of it and also a System Restore Point. Using Regedit you can search for the references to the program and delete them. That should do the trick.
BTW: This is one of the recommendations for those having difficulty with Adobe Reader 8.
You could also try Microsoft Windows Installer Cleanup Utility.
