Timeslips 2011 - installing on server 2012

Trying to install a 2011 workstation on server 2012 which is the terminal server.  Timeslips 2011 has installed without issue on Windows 7 machines but will not install on server 2012 with the following message

You are trying to install Timeslips on a workstation that is using an operation <sic> system not supported by Timeslips... see manual

The obvious answer is to upgrade but we're investigating whether we can get around this. 

Has anybody here had any experience of this and have you managed to find a way around it?
