I have been trying for the past couple of hours to install my trial version of illustrator CS6 without success. After downloading the adobe support advisor i got the report error "system restart pending" in the trouble shoot section the solution offered is to a. restart. that didn't help. b. to edit the registry by deleting the Inprogress key. well I followed the link but when I got to the location of session manager I didn't find a key by that name. so I couldn't delete it. and I'm back to square one. 
If anyone has a solution I would be very appreciative.
BTW I disabled my spy ware and firewall but that didn't help either.
Thanks in advance.
