In the most recent release of BatchPatch that we published last week (version 20210827), we finally began enforcing the requirement to have .NET version 4.6 installed on the computer where BatchPatch is run. If you don’t have .NET version 4.6 on the BatchPatch computer, BatchPatch will not be able to launch successfully. If you encounter this issue, you will likely see something similar (though not necessarily identical) to the screenshots displayed below.
If you were able to successfully run previous BatchPatch versions without issue, but then you tried the latest BatchPatch version 20210827 and discovered that it won’t even launch successfully, you probably have a .NET version issue. Please check which .NET version is installed on your BatchPatch system, and then install .NET v4.6 if you’re still running an older version of .NET.
