Customised SAP AddOn


Our teams has been developing and installing Customised SAP AddOns on client sites for testing.

However, we always encounter 2 common problems:

(a) "Another version of the program has been installed" - when trying to uninstall from SAP B1 AddOn Administration.

I notice there is SAP Notes that suggest removing 'AddOnsInstall.sbo' and 'AddOnsLocalRegistration.sbo' . However, this solution requires reinstalling all AddOns after the removal.

Is there a particular reason this happen that we can include in our program as a fix?

(b) Sometimes, after uninstalling from SAP Business One, we still see that the AddOns hangging in Control Panel--> Add/Remove Program. If we try to uninstall the AddOn from Add/Remove Program, we receive an error "Object reference not set to an instance".

Any advice on this?
