When adding a custom component (.tlb file) in ArcMap the message returned is, “No new objects added.” The methodology used for adding the component is to click Customize > Customize Mode; select the Commands tab in the Customize dialog box, and click Add From File.
When using the ESRIRegAsm utility to register a custom component (.dll) in ArcMap, the error message returned is, “Registration failed. Could not write to disk.”
This behavior occurs if the User Account Control (UAC) setting in the Windows 7 machine is set high - to, or close to, 'Always notify.'
