No I am not running it from within appdata.
As ALWAYS, with every game I DL and extract frrom the web, it goes on my E drive, an external SSD, and in the directory E:\LZ. If necessary, I create a subdirectory nmatching the games name, and then extract to it. Else, the zip upon extraction, creates a subdirectory matching the games name. THIS time, the extraction from the initial DL, created a subdirectory PUBLIC. So I have E:\LZ\Public\MoR_0815b(Public).zip\Masters of Raana
I had not noted the .zip extension after the 1st extraction until just now.
EDIT: Performing a 2nd extraction works. It now overwrote (updated???), the previous installations folder, and opens the new version. I've never had to extract a 2nd time, after extracting from the original DL file.
