On my primary machine [Linux] I just extracted the archive ZIP again.

GRE PSR-500 PSR-600 PSR-500C PSR-600C DSP 1.4.zip.png

It contains the "__MACOSX" folder with an EXE. This is the file I've tried to run on the Windows 11 laptop.

and as I said in post 20 the _MACOSX folder does not contain a file that runs in Windows. In the root of the zip file is the correct executable, DSPUpdater_PSR-500-600_U1.4.exe. When unzipped the file size should be 232 KB.

The file in the _MACOSX folder has a similar name but the first character is a period (.) and the file size is only 225 bytes. This file will not run in Windows.

Check to be sure the file you are running is 232 KB and the file name does not begin with a period. Don't run the file inside the _MACOSX folder.
