I recently made a clean install on my home computer of Windows Vista Home Premium edition. (I like it so far.) I am trying to set up a backup program to run overnight (unattended), as I do with other PCs. As advised by Vista, I normally run as a normal user, i.e. not an administrator. In the normal user environment some programs require an administrator password before they will run. I have Acronis True Image 11 installed. It will run when I manually start it. When doing that, it first pops up a Vista User Account Control popup (a.k.a. UAC), requiring an administrator's password to access the program. Once I enter that password, it runs properly. I've searched the internet a lot about the Vista UAC. The common advice is to be wary of bypassing it by deactivating UAC. There are good reasons to let Vista maintain this segmentation of user environments. I have been trying to find a means to run Acronis overnight, however, because of the UAC popup, it always fails -- unattended...I'm not there to type in the password...so it can not run. I can read the log the next morning and it basically says there were insufficient permissions to run. So, I am asking if there is a method to run Acronis as an unattended backup in Vista, while not disabling UAC. I hope that is clear. Thanks.
