I had trouble updating to a newer version of windowblinds until i saw Zuubaz's post about uninstalling the earlier version & unticking archive on update rebooting then installing new version it worked a treat,it only happened the once & after the new version of wb was installed turning on archive again was fine,just can't remember if it was updating from v5 to v6 or not when the incident occured,in your case however try turning off archive first if it still hangs,uninstall the older version as well,it would pay to make sure SDC is fully updated before anything else,apart from uninstalling the lot inc SDC(i usually dump the lot & start again with fingers crossed if all avenues i try fail..lol.. it usually works tho i also manually remove registry entries as well after using ccleaner),other than that i can't help any further,in the mean time i take it you have a cheap objectdesktop software for sale
