No virus scanner installed. tried safe mode, run as 'administrator'.
Tried 3.4, 4.0 and everything in between with no luck
Robotask lite did install. have 20 or so registered copies of 3.4 so would really like it working on that

Click on RobotaskSetup.exe and the can see the RobotaskSetup.exe in task manager for about 1 second then it closes and that's all it does.
Any advice?
