Mrmtnbk1:Missing STUDIO 12.MSI file I cannot find it
If you have Purchased Premium Content transferred to S12 from a previous Version, via S12's Transfer Wizard, particularly HFX Vols 1 & 2, there's a chance that applying S12.1 Patch will Delete them. So unless you have a compelling reason for Updating to S12.1 Patch, IMO (& others) - Don't.
Anyone-else?
