Robert,

Very many thanks - plenty of food for thought. Am about to take a short
break and so will report back later. Btw Filemon only revealed one
discrepancy:

Regsvr32: FFE9D77FF Attributes c:\windows\system\regsvr32.exe.local Not
Found

Checked properties. None ticked. Selected Archive. Ran Regsvr32 again - no
change to either DllInstall error message or to Not Found message in
Filemon.

Will be in touch after the break and once again, thanks for all your help.

Denis
