Can I have both 32-bit and 64-bit Lazarus on the same computer?

[Nekoninja]

I first installed the 64-bit Lazarus version but wondering if I can also install the 32-bit Lazarus version as well?

Will the fpc-3.0.0-win32.exe interference with the Lazarus?

Thank you for your help,

I have the same.
Just set up the shortcut with a different config path (-pcp).

Yes, as explained here: http://wiki.freepascal.org/Multiple_Lazarus#Solution_for_separating_instances_using_multiple_config_dirs

However, I believe that better and easier solution for Windows is to have only 32-bit Lazarus and compile projects for both 32-bit and 64-bit targets.

you can either install 2 Lazarus.

Or you install one, and the cross compiler add on. Then you can create and debug 32 and 64 bit apps from within one lazarus.

Does that (debugging) actually work sonce you need both 64-bit and 32-bit gdb?

I have a setup with gdb statically linked for win32 and use (cygwin64) gdb/mi for win64. No problems at all.

You might also want to know that when you hit Run or Compile, 32bit Lazarus & FPC is somewhat faster than the 64bit version. At least this was true when I tested last year.
