Why Back? You can just simply have both installed with different Installationdirectorys 
And why 0.93.3 and not 0.94.1?
I just tried 0.94.1 and it appears to be working. And why 0.93.3 and not 0.94.1?Now pls backup the guardian.exe File from C:\Program Files (x86)\Armory and install 0.95 then copy it back. Thats all
