Starting with 9.5 you can have both 9.5 and a pre-9.5 Admin and User client on the same PC.
For example, on my PC right now it used to be the only place I could ever install a client before 9.5 was in the
Start -> All Programs -> IBM OnDemand32 path
Starting with 9.5 the client will install in a different path, specifically:
Start -> All Proglrams -> IBM OnDemand Clients V9.5
So now I have two paths off Start -> Programs and I can run both 9.5 and pre-9.5 clients, fully supported from the same PC.
This is automatic when you install the 9.5 client, that by default it will pick the new path.
