If you do an install with the MSI, follow the above instructions but also note that when doing an installation with the MSI, the folder OCSSETUP isn't created in ProgramFilesFolder. Because of this, every time you start Lync 2010 it will cause a repair because Windows Installer is looking for that folder. To solve this issue, edit the OCSSETUP entry in the Directory-table and set the parent to ProgramFilesFolder and call the folder "Microsoft Lync".

Product: Microsoft Lync 2010 - Update 'Lync (KB2693282)' could not be installed. Error code 1603.
Patch error: Error 2727: The directory entry 'INSTALLDIRECTORY64' does not exist in the Directory table
Does anyone have a workaround for this so that we can continue using the transformed MSI for installation and successfully patch with critical security updates? - DreadLion72 12 years ago
