I have a product that when first run by a user tries to
write COM information into the
HKEY_CURRENT_USER\SOFTWARE\CLASSES key. If the user is a
member of the Administrator group everything works fine.
If the user is a member of the USERS group the update to
the key fails. On NT and WIN9X system the information is
written into the HKEY_CLASSES_ ROOT section of the
registry. Microsoft added the
HKEY_CURRENT_USER\SOFTWARE\CLASSES registry with the
release of 2000 and XP. Why can't a user write into their
own registry location when a member of USER group.

I believe the software is using the
msidbRegistryRootClassesRoot constant to identify location
of registry entries during a per-user installation or
first time product runs.
See

frame=true

My work around has been to export the registry info for
the key from the Admin user and import into the standard
user. I can import into the key but this program fails to
write into the key whenever I run it as a regular user.

I have thousands of users that will be upgrading to XP and
have run this program for years on NT with no problem.
HELP!!!

Thanks,
