i got 8.6 Mac OS for starters. and after downloading the installer, it upgraded MRJ to 2.2.5 (it was originally 2.1.1). Anyways, when i opened the installer after the restart from the upgrade, it gets a fourth-third way through the installation then feeds me. "The installer is corrupt. The zip archive contained in this application is corrupt." anyone else experience this bug?? how'd u solve it??
