The problem is that we are using the same Windows registry keys as
OpenOffice.org and in practice that means that both products are
incompatible and you'll have problems if you install them side by side
or if you try to uninstall one while you work with the other.

I guess we have 3 ways to adress this issue:

1. Document the problem and make users uninstall any previous versions
of OOo before installing LibO.

2. Make only a few changes in the most critical parts (for example:
HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\soffice.exe)
but share most of the keys.

3. Use a completely different windows registry keys for LibO.

This patch would be the first step for the 3rd one, but I agree that
is something that haven't been discussed yet. I guess the "big guys"
should take a decision on that matter.

Cheers,
