8.1 supports windows 7.
So does this mean that once my company implements Win7 desktop build. There will be no 7.6 OM client available?
Will it run under compatibility mode?
In the installation guide for 7.6, the matrix notes that only Windows 2000 & 2003 Server (x86), XP & Vista (x86) are supported for the Configuration and Provisioning console.
Therefore you could either use Compatibility Mode or install XP Mode for Windows 7 and use that to run the console until you are able to upgrade to version 8.0 or higher.
When using compatibilty mode, as you may know, you should set the compatibilty before you start the installation.
I can't say that either will work for sure, but I have used both in the past for some other software and it does the job.
Otherwise I would raise a support ticket to highlight the issue
