I want to use openstudio for energyplus simulations, I am using window vista operting sysytem. I down load EnergyPlus for windows vista & its working fine.. But when i installed Open STudio it give error while launching as create process failed; code 2.
I dont understand how to fix it because i couldn't see any updates for open studio to use it in Windows vista.

 Sincerely,
