Not a Valid Office Plugin

I've written a Outlook plugin that's working like a charm in Office 2016. It registers and works first time. Problem is when I try it on a Office 2013 machine. I have to manually add the plugin, and when I select the .DLL, it tells me it's not a valid Office Plugin.

I've built the .DLL with both the Office 2000 and Office 2010 units, but still no joy.

I've tried the manual adding to the registry, the regsrv32 way etc.

Am I missing something somewhere?

Hello William,

Make sure that you deploy a DLL the bitness of which matched the bitness of Outlooks.
Make sure that the DLL isn't broken.
If the DLL is signed, make sure that the signature is valid.

Hi Andrei,

Thankyou. I believe that was the issue. The script I used in Inno Setup to determine bitness returned 32-Bit for 64-Bit installations.
