That's completely up to you. I also could give you commit access so you
can commit your changes directly. You just have to make sure that you
don't commit a change which doesn't build - otherwise the nightlies
won't work. (I need your tigris.org ID to give you commit access).
Lübbe could also open an account in our issuetracker so you can keep
track of the changes you want/need to make.

I'd prefer to split the file up into several ones too. The file we have
now was originally generated with dark and edited - that's why it's all
in one file.

I don't think a warning is necessary. People just want to install the
package - they expect the installer to handle updates/upgrades
automatically.

I've already removed the thesaurus. The installer is now about 5.5MB
which should be small enough.

A change to build.bat shouldn't be necessary. Just the build script of
the installer.

Are those used in more than one place?

We don't have self registering COM components. So the GUID's must be set
in the installer. But separating them into an include file seems to be a
good idea.

Maybe it's possible to just kill a process?

If possible, the progress indicator should be improved too. Currently,
the progress indicator runs through several times instead of showing the
overall progress. Also, a text indicating which components are currently
being installed would be great.
