The Add-On is already loaded - anything else except MDID?

Anonymous

Hi guys, please help!

I have two add-ons for Archicad 22 (Windows) and the Add-On Manager keeps showing "The Add-On is already loaded." for one of them although I have generated different MDIDs for them (many times) with the generator from the Archicad 22 dev kit. Is there another setting that is used to distinguish between the two add-ons?

I have the same add-ons for Archicad 20 and 21 and also for 20, 21 and 22 for MAC but everywhere there's no problem except for 22 and Windows

Thank you! Very, very useful tool. It turned out the MDIDs are equal. I have made a wrong include of a file which was never rebuilt and so changing the MDID took no effect.

Thank you very much again!

At first I think we must make sure that not the duplicated MDID is the problem.
Please download Resource Hacker (http://www.angusj.com/resourcehacker) application. Simply drag and drop your AddOn to it and check the MDID resource: If it shows the same for both of your Add-Ons then you have problems still with the MDID.
