I know why it’s there. I upgraded from version 7.4.2.0 which was 32 bit. The update is installed over the old installation.
I have no idea if this has any unknown effects - like a WOW64 issue - but it definitely will be a confusing situation after a few months when we all forget why a 64 bit program is stored in the 32 bit programs folder.
It’s best to do a complete uninstall of AppStudio 7 before installing Version 8.
AppStudio 8 should install to Program Files. There shouldn’t be anything in Program Files (x86), but Windows is known to sometimes mess this up on installation.
Prior to AppStudio 8, the installation was done to c:\Windows (x86). Now that AppStudio is a 64 bit app, it installed to c:\Windows. The problem is in the Windows uninstaller - sometimes it is unable to work properly due to old files, links, etc.
I waited till I saw 8.0.0.3 solved most installation issues for everyone. I then totally uninstalled 8.0.0.1 as per instructions. Installed 8.0.0.3 and entered serial number. Everything was fine.
