CFX-POST not opening on remote desktop

    • Arachnid1473


      Because of the virus outbreak, I like many others am having to work from home. As such, I have been using remote desktop to access workbench, and was previously having trouble with a black screen in the pre and post visualisers. This was solved (for pre at least) by setting an environment variable as described in a previous post.

      Now when I try and open post, I'm greeted with a window saying "Application was terminated before command could be sent" and a string of error codes that can be seen below. I have tried looking online for assistance, however none have been of any help, nor do they have the same error codes as I do, and the university IT department haven'e gotten back to me either. I would really appreciate some help as my deadline is growing ever closer.

      I have attached a txt file of the error codes due to an issue with posting this question
