I am trying to update QS to version 2.7 using the download link at http://pangolin.com/support/software-updates but after running the installer program (no error messages whatsoever) and restarting the laptop, QS.exe is missing so I cannot start the program. I know I am most certainly doing something wrong, but I cannot figure out what. The old QS.exe is in the backup folder but there is no new QS.exe in the QS folder, nor does it turn up with a search on the entire harddisk. Tried twice (once without and once with installing drivers) but same result. Previous updates always went flawlessly. Does anyone have a clue as to what is going on?
