vrf Multiple VEE versions on the same PC

Question asked by VRFuser on Aug 20, 2008
Hi  Hans,

I am running VEEPRO 8.5 and HPVEE 5.01 on the same PC (Win XP SP2) without problems and all of my old code apears to have transferrred over and then modified and runs OK. Obviously, once  V5 code is saved in VEE8.5 you can no longer load it in V8.5 (and v7 upwards). 8.5 evidently works OK with MS Vista but I don't think v5 works with it. however, I am steering clear of Vista for now.

Hope this helps
