Answer 1

Did you compile it as an EXE, a runtime DLL, or Multi-Threaded DLL. Additionally, a problem I've had before is that of single or multiple instances of an OlePublic dll entry. To confirm, modify your project... then from the Top Menu, click "Project", then "Project Info". On the third tab is "Servers" showing the available servers in your project. On the right side of it is "Instancing" this would be either single or multiple. Sometimes, just throwing this to single has solved instances for me. However, if multi-threading, make sure you have the multi-threaded dll too.. VFP9T.DLL

--- EDIT PER RESPONSE... Since you compiled it as an EXE, Its probably going to show up as a distributed COM object. Go to the Windows "Start", and run "DCOMCNFG" which will bring up the DCOM Configuration manager. You'll have to scroll down the list of items until you find your exe (OlePublic class name) and might have to revise permissions, who can launch / access / execute... apply impersonate, etc...

FOR TESTING ONLY --- You could set this COM server as impersonate Administrator -- JUST TO TEST and see if any errors or not. If no errors, then you'll know its a permissions thing, then change it back to a more restricted user.
