I was wondering if anyone can help me, I have just loaded Sage instants V10 onto my computer (Vista), but I already have Sage V12 on there for another customer, I assuming because they are 2 separate programs that data will not drift from one program to another. In other words the computer won't get confused between the 2.
I have phoned Sage but didn't really get a proper answer!
I actually had two different hard drives running on my desktop at the time, and installed one version on each drive. One was the C Drive and one was an E Drive which was installed after I purchased the PC. This was fine but I think if you try to install two versions on the same drive then you will simply update the older version.
I have heard that if you set up different user accounts on windows then you might be able to load two versions of Sage on the same drive without one updating the other, although I've not tried this myself.
