Error message in 25 and 26, loads in 23, 24, 27

I am getting the following error when opening Revit 25 and 26, but not 23, 24 or 27.

pyrevit Error
pyrevit Error900×399 39.2 KB

I have done the following (several times, and not necessarily in this order):

  • Uninstalled pyRevit
  • Installed pyRevit version 6.53.2617 signed and admin signed versions
  • Installed pyRevit version 6.5.2.26175 (after uninstalling pyRevit) signed and admin signed versions
  • Restarted my computer
  • Updated to the latest version of Revit 25

No one else in the office is having an issue, and it is not a problem on my laptop.
I am an IT flunky, but I suspect it might not be pyRevit itself and something else on my computer. Very specific, step-by-step instructions are greatly appreciated! Thank you!!

Do you have .Net 11 innstalled?
