I'm trialing Fireworks CS5 while I wait for my purchased copy to be delivered and I've only been able to run it once. When I launch the application (from Start Menu or from exe) the splash screen appears and then almost immediately disappears. No errors are reported.
I have tried:
I'm using a new laptop but running XP due to corporate policy. There are no other instances of Fireworks.exe running.
The one time it worked was after one of the re-installs. At the end of the day I quite Fireworks, locked my PC and went home. Next morning, I unlocked my PC and it had stopped working.
I managed to fix this myself. For anybody else that hits this, the problem is with updaternotifications.dll. See the second half of this thread for more info:
Essentially search Program Files\Adobe for updaternotifications.dll. Rename to Xupdaternotifications.dll. Problem solved.
Seems to be related to the DLL not being able to create a "Check for updates" task in C:Windows\Tasks.
Thanks for posting your solution!
