How to install Delphi XE on Win7 64bit that has Delphi 2010 on it with least fuss

Any advice or gotchas that I should be aware of. I know 开发者_开发知识库to install in a NEW directory, and to have a backup. I will reread the readme file that included in the Delphi-XE installer.

I've never had problems installing a new release of Delphi with an older version also installed. I have heard that you shouldn't do the opposite (install an old version with a new one already installed) but as far as I know, installing "forwards" works just fine. And specifically installing XE with D2010 already present has never given me any trouble either at work on on my personal system.

Ive had a number of machines with multiple versions of delphi on without issue, however if you are that concerned, a further thought or consideration is to virtualise your development environments as then rather than reinstall you can "copy" .. Ive put mine into the XP mode machine on my windows 7 for that very reason.

I recommend not installing in Program Files (x86). I created a folder C:\DEVTOOLS which has my Borland, Codegear and Embarcadero folders (among others). This is definitely the 'least fuss' option.
