Please help? I need to update Quicktime and keep getting this error. Tried MS help, no good.
Sorry, Ms installer problem.
What firewall do you have installed?
This problem may occur if one of the following conditions is true:
The Windows Installer files that are on your hard disk are damaged or are missing.
You install or remove a program that uses the Windows Installer Microsoft Software Installation (MSI) package file (.msi). For example, this may occur when you try to install Microsoft Office on your computer.
