Windows 10 Pro, upgraded to 2.384 and now I get a "This app can't run on your PC. To find a version for your PC, check with the software publisher."
.368 is fine. Compatibility checker does its usual - nothing detected.
7-Zip is the preferred software. Shouldn't have any trouble with the DSD+ zip file/password using any version of 7-Zip that has been released within the past year or so (64-bit version preferred, of course).
