>>Thanks for the information Eric. We fixed our problem but we used the HK_LOCAL_MACHINE hive instead of HK_CLASSES_ROOT. We felt that we did not want to change the root classes because we are novices at using the registry and teh word "ROOT" scared us. Using the HK_LOCAL_MACHINE worked.

Erik (and Ken),

HKEY_CLASSES_ROOT is provided for backward compatibility with Win 3.1. That indicates to me that an older 16 bit application might not check HKEY_LOCAL_MACHINE.
