Hi,
I did use B1DE to make the installer for my addon
Everything is working perfectly in my development environment which i did install the addon with success.
As soon as I try on the client machine I got the error
Add-on MyAddon : Add-on %s - uninstall failed.
And believe it or not this error appear when I click INSTALL on SAP dialogbox and it is the first time I'm trying to install the add-on on this machine
Any idea ?
