I need to make a POC with some RPA tools, so I’ve registered at UIPath and got a try license.
After installing UiPathStudio (latest) (no version on screen, no “about box”) and trying a sample “calculator”, the only message I receive is “Permission missing; launcher”. (Windows 7 Pro 64bits.)
In the service console, the service “UiPath robot” is started and running.with “local system” credentials.
First you can find UiPath version by click after you start the studio. It should be displayed on the right.
Regarding your issue it looks like it cause by multiple version installed in their machine and seems to get solved by wiping all of them and reinstalling after.
The cause could be different but still you should give a try.
