I have some programs that are for the components in my computer, such as my\ncpu. I just tried to install the Dual Core Optimizer and received a message\nthat says "Error 1721. There is a problem with this Windows Installer\npackage. A program, required for this install to complete could not be run.\nContact your support personel or package vendor. Action:InstTool, location:\nC:\Windows\Installer\MS1779.tmp, command:"\n\nI opened another thread where I mentioned Vista x64 won't install my\nmotherboard software. Is this the reason why these type of programs won't\nrun? How can I get Vista x64 to run my motherboard software and these\nprograms? I opened D: and tried to manually install all the software but\nVista x64 wouldn't let me do that either.
