you will need to hit Continue on the annoying UAC prompt message at this point Select the last item on the displayed window which should be Turn User Account Control on or off. Turn UAC OFF by selecting Start / Control Panel /User Accounts and Family Safety / User Accounts If you've already installed FDC on your Vista machine please uninstall it. You must also be logged on using an Administration account. So, here's what you need to do and please note these instructions assume you are using the standard Vista interface and have not switched to Classic View.

By turning this feature ON I can recreate the problem each time.

I turned UAC off from day one, hence the reason why my installations worked every time. The main culprit is the User Account Control (UAC) feature which, although designed to keep your pc safe, is a little annoying to say the least. Thanks to one of our users (Dennis from Southern California, USA) I think we may now have a solution to the Error 58 problem some of you are experiencing after installing FDC on a Windows Vista machine.
