Further to my last, I see NET fw 3.5 is available in control panel/programmes/add windows features. But it is highlighted with a black box and on clicking there are two options http activation and non httpactivation?

Continuing... Have used add windows components in control panel to add in dot NET 3.5, rebooted etc. No change BCM either from download or original DVD starts GUI, does a system restore, then promply flashes, goes to the end screen as if set up but it isnt!. Can add log files if it would help.

I'm receiving the exact same problem mike, were you able to get to the bottom of this?

I just gave up. Followed all the normal stuff, and even went to windows 10 programme settings /change windows features to activate Net Framework 3.5. However, BCM just tries to install then goes straight to the completed screen. No error messages. I have since found that SQL server 2008 seems not to be compatible with Windows 10 and BCM uses SQL2008. I had thought about upgrading to SQL2014 express, but have not tried it yet. No conclusive answers from Microsoft, but as they are discontinung the programme I guess they are not interested. I you have any luck please report back
