Win95 crash problem

For some reason, my Windows build only crashes on Win95.  When I look
at the install_wizard.log file, it crashes while writing to the
registry in the "Currently installing Mozilla" module (only it doesn't
say "Mozilla" it says the name I have dubbed it).  I notice at the
beginning of installing this module I see a couple of errors which
look like:

ERROR (-238):  Windows Register Server: <Program Folder
Path>\ISimpleDOMNodeMarshal.dll

and

ERROR (-238): Windows Register Server: <Program Folder
Path>\ISimpleDOMDocumentMarshal.dll

Any idea what these errors mean?  Thanks, Dave
