Important, graphics driver issue

Following a recent (2025) Windows update, some users with integrated graphics, particularly laptops using Intel Iris Xe or UHD graphics, may experience an “unexpected error” followed by the application closing after loading a file or completing a wizard. This issue has been linked to Intel® Corporation Driver Update 32.0.101.7077.

Installing the newer Intel® Graphics Driver 32.0.101.7082 will usually resolve the problem. However, this update is not currently offered automatically through Windows Update and must be installed manually from Intel. As an alternative workaround, installing our software with the “Use software rendering” option enabled should also prevent this issue from occurring.
