Getting a couple of questions answered will save me a few hours of trial and
error testing so thanks in advance for any insight or assistance.

Application has already been installed on users computer and an uninstall
log (uninst.log) was created at the time of the initial install.

Now I want to do web updates and from time to time I may need to include a
"new" file that was not part of the original install. During the update
install could I "Open" the original log file instead of creating a new one?
If I have it open and the update installer writes to the opened file will
the items be appended to the file?

If I end up with duplicate entries in the uninstall log as a result of
existing files being replaced or patched and entries being written to the
log file, will the uninstall handle the duplicate entries gracefully or will
the uninstall crash?

Are there any other gotchas I haven't thought about?

Thanks again for any help.
