Well the install guide reads "3. Copy the folders apps, content, extension and system to AC root folder " , no JSGME whatsoever. And can anyone help me on how to activate SOL as a mod in mods section of CM?The install described in the install guide, is the safest way to install Sol. You can also use JSGME or the "mods" function of CM. The Sol install is in JSGME format. So if you like to install it with CM, just copy the MODS folder to AC root folder and then activate it in the MODS tab of CM.
Also my question is how to update the working SOL version properly, just copy n paste n overwrite the 4 folders apps, content, extension and system to AC root folder ?
