We want to test 2.0 before we upgrade our production system.
Can you have ver 1.6 and 2.0 loaded on the same box?
yes, you can have multiple installs of the software running on one system.
The second install will need to be installed in a different library and you will need to specify different ports for each install.
Also, any project that is created in 2.0 with tasks or elements unique to 2.0 will not work on 1.6x.
