Windows 7 32 bit.
Started the installation which then stopped part way through with the message 'unable to continue', followed by 'unable to send report'. This was followed with the dreaded blue screen of death!
Restarted and the installation was then completed without incident. Asked for the licence key and part way through entering it BSD again!
Restarted and completed the licence key all appeared ok. Started a full scan and after 15 minutes BSD again!
Completely uninstalled and reinstalled without incident. Started to complete the registration and BSD again!
Getting a bit fed up by now but restarted and tried to update it. You've guessed BSD yet again!
