update - the day after forcing the .net 4 install which comicrack wanted I was plagued by BSOD ( which has never happened before on this PC ) . After a nightmare day of running hardware tests, failed system restores ( due to trusteer - rapport crap) , registry restores via ERNDT,and a full repair of office & of the default .net 4 client profile ( repair via control panel) -the BSODs seem to have stopped ( fingers crossed).
that could all be co-incidence, but it's hard to find anything else to blame.
except that there was a windows update which installed when I shut down after the comicrack & .net4 install, which complicated the system restore issue.
Every random BSOD occured when opening or closing some new window on screen . it was not software specific though Outlook was a persistent offender) & was with various stop codes / messages.. I had bad pool error, page fault in non-paged area, system service exception...
I'm guessing that outlook relies on .net framework. could be that the microsoft download does not check PC specs and that it put on a 32 bit version instead of 64 bit - who knows. I think ati catalyst drivers also link into .net framework which could explain the BSODs as always there was a screen refresh involved, due to opening / closing a window.
Anyway I will not be touching the .net install again & comicrack is binned. I'm not that fussed about reading comics!
PS I did see, when googling .net 4, reports of BSOD after installing it, on another board but I can't seem to re-loacate those now.
