I am using Robotstudio 5.08.2028.1009 and want to test a RAB file. When I placed the *.gtpu.dll and the *.dll in the directory of the robot and want to start the application I’ll get the following error. I do not have this problem on a real controller.
Check this posting to see if this is the problem you are experiencing.
If this doesn’t help, can you post all of the exception text from the FlexPendant, i.e. scroll down the screen further? Also, you may be able to use the Visual Studio debugger to step through the code to see where it is breaking.
Also, you might want to re-post this in the RAB forum to ensure that more RAB users see the post.
