I've installed parallels and windows XP on my iMac in order to ease compatibility issues with work. I have Office 2008, which has installed on my Windows (vista)laptop without any problems, but when I try and install it using the virtual windows I get the following message: Setup cannot find the required setup controller file. Either there was a network error, an error reading from the CD or other installation media, or a problem with the downloaded package. My computer skiils are in graphics, and when it comes to this sort of problem I'm a total noob. can anyone help?
