No minidump files were created but it was definitely BSOD.
Actually there were 2 crashes as I remember 1 after installation with 1st forced reboot followed by 2nd crash.
Unfortunately no much further recorded info to base conclusions on except the event viewer which recorded only something before 1st crash that the Avast Antivirus entered the running state and after reboot several rundll32.exe - Application Error : The application failed to initialize properly (0x80000003)…which was stopped with forced 2nd shutdown and successful reboot into Safe-mode.

Did the install over again and this time also registered it for updates until 2012.
Ignored that in previous install. Also performed a complete update check of engine and definitions and the program.
Further non-defaults of an express Install: Unchecked “Improve Avast” and “Include Google Chrome” check-boxes , same as in previous install.
This time no crash after reboot :slight_smile: Could it have been due to ignoring registration?
