I upgraded to Parallels 20 yesterday and immediately could not perform batch resize or batch rename basic functions on ACDSee 2024 for Windows running in a Win11 VM on a MacOS 14 machine. I confirmed the fault by installing Parallels 19 again ... everything back working normally. Looks like something to do with permissions not allowing ACDSee to write changes to the files it's pointed at. Hopefully this will be addressed in the next Parallels update.
I'm having issues with opening photo editors on the Mac side from within iMatch on a Win 10 VM (they don't open.) I had thought that the problem may have been Sequoia, but I can confirm the problem is Parallels 20 (no problems with Version 19 in Sonoma or Sequoia.) I am also now seeing graphics issues with 20.1 (which didn't fix my initial problem) so even though I'm not using ACDSee and can't comment directly on that, for me 20.1 is worse as I now have 2 problems (graphics issues and apps not opening.) Thankfully I have a backup and can stick with version 19 for now.
