Apparently there is a problem with some--not all--installations of XP with the Adobe Updater Version 6, which can cause a big headache (read about it here:
Error "Adobe Setup has stopped working," when attempting to install updates for Adobe CS4 products (Windows Vista)) Although the Adobe Knowledegebase article mentions Vista, it also affects XP. Oddly, the current updater works fine in my Vista computer...go figure...
I ran it on a Dell laptop with Dell OEM XP PRO SP3, and it ate my CS4 Production Suite installation...if you get a message saying the update failed, continue install? --- DON'T! It corrupts the files it's updating. Adobe's advice to delete the updater files and do a removal and install was a disaster --- CS4 Suite re-installed with numerous errors. Fortunately I have an external clone drive and was able to dump the whole drive and install the clone, but it could have been much worse. I am able to install the individual updates, downloaded direct from Adobe without using Updater, with no problem. My updater was ver. 6.0.2.
Just a warning. Apparently this only affects some OEM versions, but it's a bad problem for which Adobe at present cannot define a cause. / Battle Vaughan /miamiherald.com video team
