Uninstaller "Error lauching installer"
Using NSIS 2.0 beta 3 and everything was working great.
However suddenly today all my "Uninstall.exe" have started to fail with a popup titled "NSIS ERROR" saying "Error launching installer" with just one OK button.
The installers and uninstallers are simple, no callbacks, etc.
Any clues anyone how I can start to debug/solve this ?
Even the NSIS uninst-nsis.exe gives the same error.
Have rebooted PC, have re-installed NSIS, still no joy....
