Cannot load Add-on in Excel

[TheFlyingBox]

The installation is executed just fine but when opening excel the Add-on is not loaded, and when I try to run it, there is a runtime error. Any suggestions as to what I did wrong ?

You need to be admin on the machine during installation and install "for all users".

[TheFlyingBox]

Thanks for taking the time to answer! I am surely still doing something wrong... I am admin on the machine, and ran the installer as administrator (cannot find the "install for all users" option)

But I still get the same error. Could it be linked to the fact I needed to create a new certificate as instructed in this closed issue ? "Cannot build project, pfx is missing #1"

[barnstee]

It won't build an installer (setup.exe, etc.) without the cert, so since you got the installer, you have a cert. What does the runtime error say?

I managed to get this :

So sorry, I found my mistake... The build was set to "x86". I switched it to "Any", and now everything works ! Sorry for the trouble. And thank you for this great Add-on !

[barnstee]

Ha, was just about to reply this is the classic processor architecture mismatch! :-)
