"This program does not support the version of Windows your computer is running". WIndows 7 Professional installed.
My problem reproduces also with Oberheim SEM installation. All other plugins installed fine.
EDIT: It seems itīs all about Service Pack 1 on Windows 7 (if you donīt have it installed, both Wurlitzer V5 and Oberheim SEM V doesnīt allow to install showing "This program does not support the version of Windows your computer is running" error message).
SOLUTION 1: Install Wurlitzer V 1.0.3 (version for Windows XP or above) and Oberheim SEM V 1.1.3 (version for Windows XP or above) , and it will run on your Windows 7 x64 without SP1
SOLUTION 2: Upgrade to Windows 7 x64 SP1
