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.

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 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.

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.
