My Win7 now installed RAD Studio 2010 with Delphi 2010, can I install Delphi XE3 separately? So both Delphi 2010 and XE3 work on the same Windows?
Thanks!

Yes you can. You can install all versions of Delphi side by side on a single machine. I'm currently sitting at a machine with D6, 2010, XE, XE2 and XE3.
Different people have different ways to organise side by side installations. I personally remove all references to Delphi from my system PATH variable. Then if I need to do anything at the command line I make sure I execute the rsvars.bat for the target version. That sets all the environment variables needed for that Delphi version. At that point executing dcc32.exe results in the target version of the command line compiler being invoked.

They should work. However some certain components might be buggy like different versions of BDE or maybe different versions of remote debugger core. But in general if you install lesser version with updates and then install more newer one - it should work. Unless some bugs happen.
But when you'd compile your projects or libraries, if you want to use both IDEs you should be very accurate about DCU and DCP paths, BPL names and such, so they would not be mixed in same place. DCU and DCP should be written into and searched in different folders. BPL names should have version-denoting suffix to them. and such.
