I welcome the new facility in Lightroom Desktop to edit images in third party apps, but ran into a problem the first time I tried to use it on my Windows 11 Pro PC which has Affinity Photo installed. Pointing LR to affinityphoto2.exe produced a "Cannot access this file" error.
My understanding is that some apps are now sandboxed when installed in Win11, and AffinityPhoto is one of these. Lightroom is not the only application to have run into problems as a result.
I have found this conversation https://forum.affinity.serif.com/index.php?/topic/171826-why-are-we-using-msix-for-windows-installer... on the Affinity Photo forum, which offers a utility called aflaunch.exe to resolve the problem. I am aware of the risks of running utilities from "unofficial" sources but I tried it, and it works for Lightroom Desktop to open images in Affinity Photo. Try it at your own risk, though, I can't vouch for the utility.
My problem is solved, then, but I thought I would pass this on for what it is worth. Maybe Adobe could look at the issue and check with Serif that my approach is the correct one.
