Hi Claude

Thanks for your quick response.

>For a COM EXE, you typically need to DCOMCFG it.

Could you explain or provide a link regarding this. I am a total newbie for COM and this was generated when I included a 3rd party class for managing FireBird databases, so I am totally in the dark to top it.

>Include the TLB and VBR - that's all you need to do with them. If this was a vfp mtdll, you'd need to register it only (no DCOMCFG).

Just an idea, should I tell Inno to register my exe also?

Please advise.
