MPluginmanager trouble

[zeep]

I just downloaded and installed MPluginManager because i want to install MAGC.

But there’s a problem. It can’t install MAGC unless i update existing V16 plugins to V17?
Why do i need to update V16 plugins if i only want to install MAGC?

All plugins use the same core files, so they need to have the same version installed. You can either update all your plugins or use the installer of your currently installed plugins. You can get old installers here. https://www.meldaproduction.com/downloads/all-versions

I see. I'm ok with updating them but i have customized all the melda plugin GUI's, i'm afraid updating will change them again.
