RE: Different versions of LilyPond

[James Lowe]

That sounds awfully complicated (and one would question the legality of having 
multiple installs of the same version of XP on one machine but I haven't read 
MS's EULA)

Can't you just

1. install version 2.12.whatever
2. rename lilypond dir accordingly
3. install ve4rsion 2.13.whatever
4. rename lilypond dir accordingly

and just put back the old dir name for the version you want to use.

I believe pretty much everything is self-contained.

I'm interested in running multiple versions under Windows and I think the
easiest way would be to create virtual machines to run each version of
LilyPond.  You would have to download Microsoft's Virtual PC and create
virtual hard drives for each of your versions of LilyPond.  There's a
Sysinternals utility HD2VHD that will allow you to convert your hard drive
to a VHD for use in Virtual PC.  However, you need to have enough RAM and
hard drive space on your XP host PC to create the virtual machines.  I think
using 512 gig of RAM and 40 gig for a virtual disk may be enough.

If you are using an XP host, make sure you download the XP version of
Virtual PC as Microsoft has a different version of it for Windows 7.

I just got a laptop with a Core i7 processor running Windows 7 with 8 gig
RAM and a 500 gig hard drive so I'm going to see if I can use XP mode to
bring up different versions of LilyPond as I would like to see how my 2.12.3
stuff works under 2.13 after running convert-ly.

HTH,

Keith
