Converting to 64bit Version of Sage 100
If you installed the 32bit version of Sage 100 on a computer running the 64bit version of Windows, you can convert it to the 64bit version. You should do this only if you are no longer using any earlier 32bit versions of Sage 100 installed on the same computer, and if all of your Sage 100 workstations are running the 64bit version of Windows.
All versions of Sage 100 released before version 2021 are 32bit.
Warnings!
 If you have an earlier 32bit version of Sage 100 installed on the computer, it will no longer work after you convert version 2021 to 64bit.
 If you have any Sage 100 workstations running the 32bit version of Windows they will no longer be able to run Sage 100 after it has been converted to 64bit.
Do not convert to 64bit until after you’ve completed your testing and have created a backup of the data from your earlier version.
