In the last version 2018.1 I used to launch processes from CMD using the (uirobot + file path) command with no problem but when UiPath got updated I could no longer do this, there is another question on the forum that points out to the same problem but only for the excel activities.
I tried creating new processes and launch them to see if it is a compatibility issue, and for my surprise the simple processes have worked fine, but then I tried adding other activities and this time it got stuck with the same way as my old processes.
Till this moment I see that UiRobot from CMD works fine with activities from System and UI Automation but this is not the case for the other packages.
Finally I tried to publish my project then run it and IT WORKED!!! regardless of the package
I hope someone can give me a clear explanation, UiRobot should work fine from CMD without publishing, and this was the case for the previous versions.
