I have Windows Vista
I've tryed the following:
1 - uninstall everything the uninstaller lets me
2 - deleting the programs\line6 folder, the start menu line6 folder, and the 500x edit dektop shortcut
3 - reinstall the software again so that the uninstaller would detect the Edit software allowing me to uninstall it after
It doesn't work...
I'm not confortable with deleting regitry files so i'll leave it for now...
Hopefuly line 6 will solve this in an upcoming update... The uninstaller should remove everything...
