I am having problems installing a upgrade NetObjects 2013 on a new Windows 7 64 PC.

I have followed the installation process which seems to complete ok, but when I click to launch the 2013 applicication nothing happens. It shows as running in the processes section. (Task manager) but nothing in applications.

I have tried several installations. Used a third party to uninstall everything (registry etc). Tried installing the 2013 updates before instalation/launching etc. Made sure to update version 12 before instillation. Incidentally version 12 work perfectly. Tried disabling the tablet thing. (Long shot) with no joy.

I have checked my firewall, and made sure 2013 is allowed etc.... I previously ran 2013 and 2012 on an old vista PC with no issues. Really at a loss as to what to try next. All other programmes run fine. Also I have tried changing the setting to run as administrator as recommended in other posts, again no joy.

Any suggestions would be much welcome, and thanks in advance for your time.
