The following instructions came from:
Note: Please be aware that modifying the registry improperly can cause issues with your computer.
1. Click Start, Run and type regedit. 2. Within the registry, open the below key.
3. Within the above registry key, select the program you wish to uninstall from the right side of the window.
Let's assume I want to uninstall a program that is not working, so I can start fresh...re-download and re-install. I'd try Add/Remove first of course. Let's further assume Add/Remove (after 2-3 tries) says it can't remove it. Let's say the program is Macromedia Flash Player.
So I go into the registry as per the above instructions. I go to where I can see the list of programs I could uninstall. Macromedia Flash Player is not there--no Macromedia...no just 'Flash Player'. So I go on down and I find a Shockwave folder and nested in or under that a folder call 'authorware'. I also find another folder in the primary uninstall list--that is, it is not nested--called Shockwave Flash. When I click on any of these folders, I see 3-4 entries on the RIGHT side of the window, all preceded by the lower case
letters ab. OK. Let's say I want to uninstall 'Authorware' and "Flash Player'--the works. I would highlight those right side entries and then go edit > delete--is that correct?
It's what instruction #3 above said...but for my edification, why would I just not delete the folders in question on the left side?
Final question; If I follow the instructions, is that a guarantee the program(s) will be uninstalled or can that be a risky assumption?
