I just ordered a RS licence to be able to use the new simulation option.
At this point i still have 12 days left to test…
But on my system Windows 7 x64, the Signal Analyzer doesn’t start at all.
(The product manual recommends Windows 7 x64)
On a windows XP based machine it runs without any problem ☹
What can I do ?

There should not be any problem to use RobotStudio and Signal Analyzer with Windows 7 x64 (I am using it myself).
Is the Signal Analyzer button disabled, or what happend when you try to use it?

The buttons are present but nothing happens when trying to use them, no error, nothing.
Tried it on a XP machine with no problems (both without a licence).

De- and -Installed RS, but still having the same problem.
Buttons are not disabled, and can be pushed but not functional ☹

If you have a valid license I don’t know what your problem can depend on. Please contact your local ABB office for support with this problem.
