Must get this thread out of the sink again ...
After ultra sigma worked for me for quite a while (it only spun now and then) it has not worked since yesterday.
(Still with the same Win 8.1 64).
It can start, I can also enter the ip of my scope and it will be found and added to the device list,
but as soon as I open the context menu with the right mouse button, ultra sigma crashes.
And most of the time before I do anything e.g. choose ultrascope.
Unfortunately, the tip with a dot instead of a comma as a number separator is of no use (previously it was also possible with a comma).
An uninstallation and new does not solve the problem.
The installation routine runs error-free with everything (including the NI components).
However, it is no longer possible with the error as described above.
