Here's my "trick" for uninstalling those problem buggers!
First, go and get a copy of Total Uninstall
- Last freeware version here: http://www.aplusfreeware.com/categories/util/uninst.html
- Shareware version here: http://www.martau.com/
Then, backup your registry and hard drive (in case of problems) and attempt to uninstall the program - let it remove whatever it can.
Then go diving into the registry and hard drive to eliminate all traces of the program and it's authors (You can skip this step and try the rest to see if it works, then - if it doesn't - you can come back and try this step).
As I said, be careful or you'll end up like me the other day - with a system that wouldn't boot - and I didn't backup my registry so I had to do a clean install!
Once this is done, install the offending program again - BUT, this time monitor it using Total Uninstall! Then, immediately remove it with Total Uninstall.
Then, check the Total Uninstall log file for what it wasn't able to remove - and remove it manually yourself.
I've done this with many programs, and it has worked well for me. Here's some of the problems that you may encounter while manually removing items:
1) File won't delete
2) No permission to access file
2) No permission to delete file
3) Registry key won't delete
4) No permission to access registry key
4) No/insufficient permissions to delete registry key
I've encountered all of the above - and there may be more! They all have workarounds, but a too complicated to address here.
