Haunted by the ghost of a PDM Add-In

Hello, everyone. I’m developing a Solidworks PDM 2022 Task Add-In, but I’ve run into an error that is preventing me from testing or implementing any tasks. When I try to add a task, modify a task, or run a task from the PDM Admin Interface, I get the following error:


I have removed ALL PDM Add-Ins since this error began to appear, but it persists anyway. I’m fairly new to this, so I apologize if there’s an obvious solution or additional information I’m leaving out.

There are several reasons why this could happen.

Most likely, the process running your add-in is operating at a different UAC level than PDM. For example, avoid running the Administration Tool or Explorer as Administrator.

Also, it looks like your add-in doesn’t have a name, which can cause issues — especially with how it appears in the dialog box.

Without more details, it’s difficult to provide specific help. Feel free to share more context and I’ll take a closer look.

Following a reinstall that did not fix the issue, I was able to determine that the problem is local to my machine. I nuked PDM from orbit, uninstalling it and deleting all PDM related files in Appdata and PDM related registry entries. Restarted my computer and reinstalled PDM, and now it seems to be working!
