Actually that isn’t that much of a joke for this poor guy. Vista is now on the official abandoned OS list. So it is going to be hit or miss to get many things working. Even Mozilla and Firefox have abandoned support for them. Google and Chrome gave up long ago. (I am having to migrate a few clients off of perfectly good PCs because of the dead-end of Vista)
First suggestion for OP - stick to v1.4.2 of Picard - "If it ain’t broke, don’t fix it"
Alternate options - I am not sure why you are being blocked from editing your own files in %APPDATA% folder. Have you setup a paranoid level of security on there? Or are you trying to edit this while Picard is running?
I notice the main fault is always spitting out errors on the Python code. Maybe you could manually update Python as I doubt the new installer will be testing for Vista due to it being out of support cover.
As you moved those plugins away and still go the crash I doubt they are at fault.
I can’t find any “recommended spec” pages for Picard. I have no idea if it has been tested on Vista. Kinda doubt it to be honest.
I also can’t find which version of Python is required for Picard. Or even which Python’s work on Vista. Documentation for both projects seem to be lacking specs (or I can’t find them on a quick check)
The devs can answer that question better than me.
Weird little idea… run the Picard Installer but this time do a right click and “Run As Administrator”. Looking at the python support pages Vista has to be treated different to other WinOS versions.
Confirmed that Python is version 3.5 and built into the Picard Installer. So we’ll ignore the above…
If I get a chance I’ll fire up this old Vista PC I have sitting behind me. Due to be scrapped. Can’t remember if it is 32-bit or 64-bit on there but I can at least test the installer.
