Uninstall add-on developed through B1DE.

[former_member258724]

I got a message when I tried to unstall add-on which is developed on vs2003 with B1DE.

I uninstall add-on through B1 add-on administration and got this error message during the uninstallation.

I found the add-on is gone in B1 add-on administration but still in the "add/remove programs"

so I tried to uninstall it through "add/remove programs" manually.

I can not reinstall this addon unless the previous one has been uninstalled.

Here follows the error message:

An exception occurred while unstalling. This exception will be ignored and the uninstall will continue. However, the application might not be fully uninstalled after the uninstall is complete. --> Object reference not set ro an instance of an object.

Thanks.

Hi Poseidon,

To uninstall addon you have to first remove your addon from addon administration in SAP B1, and after that restart your SAP B1, when SAP again restart it will automatically start uninstallation of that addon.

don't try to unistall addon through add-remove programs.

Hope it will help
