DSim error: "ld: cannot find C:\Program: No such file or directory"

I'm new to DSim Studio. When I try to simulate Altair's uvm-hello-world-main example I get the following error at the end of Elab1. I'm using Windows 11.

  Found 6 unique specialization(s) of 6 design element(s).

Simulation time precision is 1ns.

ds_ld  Altair DSim version: 2025.0.0000 (b:S #c:32 h:e6a01125e5 os:msys2_)

I don't get this error when I run it with the Linux version of DSim Studio via WSL (Ubuntu-24.04) on Windows 11.

The UVM error is a known limitation for Windows machines:

This limitation will be removed in the next release of DSim.

DSim 2025.0.1 fixes this issue and can be downloaded from Altair Marketplace here:

If you don't want the installer to overwrite your existing DSim installation, please make sure to change the default installation path.
