Delphi & Lazarus both installed

Just a quick question for those of you that know. Is it possible to have both Delphi (ver 7) and Lazarus installed at the same time. I want to make sure the Lazarus install will not interfere with my current Delphi install in ANY WAY. I would have asked this on the Lazarus fourms but thought I would get quicker reply here.

Anyway if you have both Delphi & Lazarus installed please tell me any problems you have encountered (if any) thanks.

I currently have Delphi 5 and Lazarus both installed on my Windows 7 laptop. As near as I can tell they don't interfere with each other.

I don't really use Lazarus though, as I prefer Delphi 5 which is what I've used forever.

Lazarus does not interfere with any version of Delphi, they can live along very happily.

The only interference is for commandline building, both projects have a make.exe file which are not the same.

This is easily solvable by not adding FPC to the path (removing it via control-panel system), and do a 

set PATH=c:\fpc\2.5.1\bin\i386-win32;%PATH%

or wherever you installed as first line in your batch files.

I generally don't bother, but a previous employer we did a lot of cmdline building with dcc, and then it matters.

File associations are another, but already named. (but not such a big problem since the project extensions vary (.dpr vs .lpr, .dproj vs .lpi) )

Btw: Other development products (cygwin,mingw, and maybe even VS) have their own respective make.exe files and the same kind of problems.

I have Delphi 2006, Delphi 2010 and Lazarus installed. No problems at all. I am sure Delphi 7 will be the same. The only problem I can see could be the use of .pas extension in Lazarus. I mean because of association problems. But you can use a different extension for Lazarus (free pascal) source files. I think the installer asks you that.

I have Lazarus "installed" on a USB drive. It interferes with nothing whatsoever. It is actually a checkout of the Git repository that mirrors the SVN repository. I installed the latest stable FPC to C:\FPC, and then copied that folder to inside my lazarus source folder, e.g. \lazarus\FPC\ (and then uninstalled the C:\FPC installation), and then whenever I like I build the latest lazarus like this:

X:\lazarus\> git fetch
[...fetch messages...]

X:\lazarus\> FPC\2.4.0\bin\i386-win32\make.exe clean all
[...compiler output messages...]

X:\lazarus\> startlazarus
[...IDE starts up...]

The main advantage of this is that if you find an IDE bug, the source is immediately available and you can make and submit a patch instantly.
