XE7 64-bit not working

[denville]

Can't install the update !!!  To be more precise..

I uninstalled the previous version (15.0.17) and ran the bundled removal tool just in case (it didn't find anything to remove).  I downloaded the latest 15.0.19 from the link you sent me.  It seemed to install perfectly, correctly recognising my copy of XE7.  Ran to completion and confirmed the licence.

Fired up XE7 (CPB) - no sign, nothing in the start-up splash screen which used to display the .17 version, no IW application option.  Re-started the PC, still nothing.  Uninstalled, installed again (again apparently successful) - still nothing in XE7.
