I ran Repair Windows by tweaking.com. It says it’s fixed a number of issues and reset some Windows internals to its defaults. As a result I had to re-set the default apps and other personal settings to my liking.
But the main thing is that re-installing Gravit Designer 3.3.1 did not provide me with a workable program,
Same error 0xc0000005.
Also re-intsalling the MS Store version didn’t give me much luck.
It installs alright, but does not start (without even issuing a warning)
Please note that Gravit Designer is the ONLY program I’m problems with.
I am reluctant to do the Windows re-installation, including all the effort to re-install all my programs and apps and personal settings.
