Can Delphi 2009 be installed on the same machine as Delphi 2006 or Delphi 2007?

Question

Is there any conflict?

Answer 1

Should not conflict.

Answer 2

Appears to be no problem. Installed D2009 with TurboDelphi and 2007 and 2, 5 and 7 all on the same Vista machine

Both 2007 and 2009 have Jedi JVC and JVCL installed on them. All appear to work fine. Hope that helps.

Answer 3

CodeGear stated (don't have a link handy, sorry) that there should be no conflict. I haven't yet installed D2009 on my workhorse PC so I don't know if that is correct.

The settings in registry have different path and packages have different names so there really should be no problems.

Answer 4

Installed D2009 Enterprise on VMWare instance running Vista Business with an existing D2007 Enterprise installation. Perhaps I did something incorrectly, but I began to experience errors in the D2007 IDE, as well as a very strange error, unknown fieldtype, in exe files compiled with D2007. I uninstalled D2009, and the errors have gone away.

Answer 5

Should be fine. I have Delphi 7, 2006, 2007, 2009 with 3rd party libs Dev Express and Rem Objects for all (except Dev Express for 2009 - is it out yet?) and all work flawlessly. As others pointed out the versions were installed oldest to newest.

Answer 6

In theory, it's possible, but if you use many third-party (or your own) libraries, it can get hairy pretty fast. I tend toward developing on Virtual machines, for this and other reasons. But, YMMV.
