Mr TK How,
It is possible to have a single installation, a desktop client as we call it, (use a multi databse tool) and make a connection to various ManagerPlus databases. It can only make one connection at a time, but yes a single installation can support multiple databases of ManagerPlus.
For example we have helped customers that wanted to try or test a new version of the program and retain the original version.
We then create a test database with them, get them a temporary license, say 60 day trial for the test database and then connect the client to both db’s. then you can choose which Database to log into test or production.
Thanks
Duaine
