Generate Simulation Setup Script Fails

When I click on Tools>Generate Simulation Setup Script for IP the messages window reports that the command runs and says "Process finished" but no scripts are created.

This last worked about a month ago. No changes to the computer except for MS updates. When I tried running this command this week, it failed to update the scripts. I created a new project with a Nios V and tried to generate the scripts, and it didn't create the Mentor/msim_setup.tcl or Mentor/run_msim_setup.tcl, or the common/modelsim_files.tcl scripts. 

I updated to Quartus 26.1 (was 25.1.1) and still no good. 

OS is Windows 11 Pro Version 10.0.26200
