Hi,
I fixed my problem. I went back to the first 1.8.9-2 version (PI-windows-x64-1.8.9-2-20230828-c) I had in my download folder. The install window looks significantly different that the current build. I was able to run the install and test the program. I then just installed subsequent versions (1+1605) over that. I lost only one process, the GHS, which I quickly reinstalled. Thinking back, I have no clue what happened. It all started when I wanted to load Seti Astro's "statistical stretch". It did not load and I was instructed to update to the latest version of Pixinsight. It went downhill from there.
Thanks for your efforts,
Bob
