is this kind of situation possible?

i quoted this from the Microsoft Press book,

"When you deploy multiple versions of the same assembly, all versions can execute simultaneously."

how to do this? what i want is to open one instance of the windows-based application on the first version, then i want to open another instance of the same windows-based application that is the second version using the same machine in the same time.

thanks a lot for your feedback first.

cheers,

problem here is i've a windows-based application created using vss2005, i try to deploy one first version 1.0.0.1, then i modify abit on my application and change the assembly and file version to 1.0.0.2 and deploy again. i backup the first version in another folder and run both version simultaneously but only one instance is on. 

then i try to change the build, minor and major versioning number and the result is i can only open multiple instances (windows) for the major and minor changes. for the build and revision changes, i can't open more instances for these cases.

is there any documentation on microsoft on why such cases happen? or can any evangelist tutor me on this?

thanks a lot in advance.

cheers
