Recently purchased boxed Movie Studio Platinum 8.0a / DVD Architect Studio 4.5a. Following install, updates 8.0c and 4.5c were downloaded. Most surprised to find that the default extraction folder was a new Setup folder created within Program Files! In my experience setup files are almost by definition temporary. Because of the unusual location I queried Sony Tech Support as to whether I could safely delete the Setup folder following the update. I am aware that a similar question has been asked before within these forums and, as expected, the answer was delete if required. However, Sony Tech Support came back with the reply "You do not want to delete the Sony Setup folder because it still contains key data needed to run the software". As the folder appears to consist of no more than updated versions of the installer and cab files that are in the setup folder on the original CD, I find Sony's answer hard to accept. Have requested confirmation but cannot get a response. Thus can anyone confirm, for these two specific applications, that I can safely delete the setup folder created by the extraction of the update versions.
