I reluctantly decided to try to upgrade from ZASS 7.0.483. I had learned from my problems with that upgrade to start by unchecking the "load at startup" box, booting into safe mode, doing a " /clean /rmlicense" uninstall, following the procedures in Message 103 to search for and delete the specified za files, emptying the recycle bin, and running "zabegone.reg"
Despite that, and after booting into safe mode to do the ZASS install, the installation had barely started before a box popped up saying "Could not load DLL library C:\.......\vsutil.dll . This application has failed to start because application configuration is incorrect."
Since I had gone to the Setup file download via the update button in my ZASS7, I assumed that my clean uninstall had made that the wrong file to use and went directly to ZA website and downloaded the 15-day trial version. I redid the Message 103 procedures and tried to install from this new download (in safe mode). I received the same message.
I then repeated the Message 103 steps and reinstalled ZASS 7.0.483.000, without any problems, and reinstalled my saved settings (and of course reupdated).
Since I had been downloading with firefox, I used internet explorer to again download the 15-day trial version. I then compared in DOS the IE download file with the firefox download file, using both the "comp" command and the "fc /b" command. The files are identical.
