The CS5 extension manager documentation states that
Extension Manager CS5 supports updatable extension packages, which allows end user of extension to update extension once there is new version available.
The document goes on to describe how you can enable this feature by including a link in an MXI file. Is it possible to do something similar with ZXP packaged extensions? Or will end-users have to uninstall old versions before installing updated versions of an extension?
You can use an MXI file to repackage a ZXP...
Thanks. I'll try that.
