Hello,

I've created a plug-in for Outlook and created an installer with Innosetup.
I've tried installing it on the most recent version of Outlook in a virtual machine and it works correctly.
Now I tried to deploy it to a customer.
De installation runs without a problem, but the plug-in is not visible in Outlook.
I've tried registering the dll with regsvr32 without a problem but still not visible in Outlook.
It is not listed in the plug-ins also.
I changed the settings of macro to allow everything and also checked to apply this to plug-ins, but still no luck.

As last I tried to add the dll using the com add-in screen in Outlook.
When selecting the dll, I get not error, but it is also not displayed in the list of plug-ins.

What could be the reason for this?

Thank you,

Bernaert Dominique

Hello Dominique,

Is the add-in per-user or per-machine? Do you install it using administrative or standard user permissions?

Hi Andrei,

I install it with InnoSetup with Admin rights.
Concerning the add-in, currently RegisterForAllUsers is false.
Should I try with changing this property?

Hi Andrei,

The plug-in is per-machine.
There is no special code in the project source.

You should do this only if this is in the requirements you implement.

A per-user add-in installs only for the user who runs the installer. If the user is an admin, no per-user add-ins load if the host application is started elevated (=using the 'Run as administrator' option); this is by Windows design. Check the shortcut you use to start the host.

This contradicts to RegisterForAllUsers = false. A per-machine add-in must have RegisterForAllUsers := true.

Thank you Andrei,

The problem is solved by setting RegisterForAllUsers to true.
