Renaming your copy of RTW and placing it somewhere completely different is a safety measure. BI has an auto installer and has been known to become 'confused' when two copies reside in the same place ( even if one is renamed ) I only had one install of RTW so no problems but the auto installer caused problems in one case that I am aware of. No idea why they chose this method, IMO manual intervention is far safer and more certain. Good luck
