When you try to update you probably see this screen…
Click OK, then follow the instructions that are shown as pop ups. Follow the advice exactly. Try again to upgrade and let us know what happens.
@dkalamata Dimtris, an update issue is sometimes that a computer has insufficient memory for the updated Companion software… could it be that the computers that do not update are older and have less memory? Are the problem computers very different from the computers that update properly?
