When attempting to install User desktop Experience on Server 2012 for Exchange 2013 I keep getting the following error. Using the GUI or powershell same result.

the request to add or remove features on the specified server failed. installation of one or more roles, role services, or features failed. the component store has been corrupted. error: 0x80073712

Hopefully this is and easy one.

Thanks in  advance for your replies.

You need to scan and repair the Windows Components store using the DSIM tool:
DISM /Cleanup-Image /CheckHealth
DISM /Cleanup-Image /ScanHealth
DISM /Cleanup-Image /RestoreHealth

If using WSUS, make sure it is turned off for this server as you will need the full Update Services from Microsoft to ensure all updates are downloaded to repair the store.

I wouldn't even bother with doing any troubleshooting.
Unless this server is already in production, wipe it and rebuild it. I work on the basis that the server should be error free from the start.
If it happens for a second time, then start looking at external influences, such as a suspect source file.

Work well for me with /OnLine option :

DISM /OnLine /Cleanup-Image /CheckHealth
DISM /OnLine /Cleanup-Image /ScanHealth
DISM /OnLine /Cleanup-Image /RestoreHealth
