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

Question

Is there any conflict?

Answer 1

The installations won't interfere with each other, although the Delphi 2009 and Delphi 2007 projects are not compatible, and can't be shared.

Answer 2

I have at least 4 Delphi versions on one machine. They do not bite each other.

I always install older versions first because i had once problems if i did this the other way round.

Answer 3

I have Delphi 2007 and I have installed 2009 yesterday with no visible problems so far. Both seem to work fine.

Answer 4

Install them in their own directories, and make sure you keep package binaries separate, you should be fine. I've got 2009, 2007, 2006, 7 and 5 all on this machine with no issues.

Answer 5

.. and if you compile existing packages make sure you give them a new name (e.g. suffix with D12) as each version's BPL directories are in the path.

Answer 6

I am running 2007 and 2009 on the same machine (this machine) just fine. The only problem you might have is if you are compiling components to the same directory - you will just need to rebuild all your DCU's and packages each time, or make version specific packages and directories.
