Just in case these are important. Sorry about the size.

You really do need to be very very careful when using a registry cleaner
especially when you've deleted folders placed in the C;\Program Files by
Windows when installing Win Me.You've fallen into the trap that many
others have fallen in to over the years.  If you backed up the entries
deleted by the reg cleaner try restoring them, especially the VARLID key.

I've attached a zip file containing a reg file containing all of the
required entries.  Download this, extract the reg file and merge (right
click on the reg file and select "Merge") with the registry and this
should hopefully fix the problem.

This problem can be avoided in future by not deleting the folders placed
in Program Files during the installation of Win Me but more importantly by
not deleting any values in the key
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\VarLDID
when using a registry cleaner.

What happens is that if any of the folders referred to in VarLDID (you can
see them by opening the reg file using notepad) is deleted then most
registry cleaners will remove the value (entry) in the VarLDID key that
refers to that folder.  This is because the registry cleaner considers it
to be a "dead" entry since the folder no longer exists.  Setupx then has
problems because if can't find one of the paths it needs and then gives
the error you saw.

I hope this helps and solves the problem.
