As previously stated by Microsoft a while ago, MS Desktop Runtime versions 8 and 9 have both ended their support on Nov/10th/2026; and yesterday very evening, ("Patch Tuesday"), they've received thei last security patch. Now, here's the issue: PMPC won't launch neither work without MS .NET 8 Desktop Runtime: I managed and uninstalled both 8 and 9 runtimes and replaced them with new ones (actively and currently supported V10 and latest V11, the latter released yesterday) with no positive result at all. Looks like PMPC can only work with V8, it's bound at it and has not forward compatibility with newly released MS .NET Desktop Runtimes Versions. All these said, I - conclusively -kindly ask you tto upgrade the app and make it compatible with newly released runtimes versions: it seems to be highly advisable and, last but not least, not only for compatibility reasons but (mostly concerning!) security ones. Thank you so much for reading my very long ("Verbose", going with MS) technical query.
