From one of our developers:

On Windows 10

"When opening Ranorex and loading the data I get this exception. Reinstalling not changing anything, I can't use Ranorex"

Code: Select all

What to do? Are there more logs that might help? Couldn't find any.

The rest of us dont get this kind of exception on startup, usually we get them while working with studio but we can restart and its fine again.

Hi wunderlich,

"When opening Ranorex and loading the data I get this exception. Reinstalling not changing anything, I can't use Ranorex

What data are you exactly trying to load?
Are you able to start/run other projects on your machine?
