I am Unable to install MS Office 2010 on my Mac

With the use of windows 7 Ultimate through parallels 6 on my Mac that uses Snow Leopard operating system, the machine works perfectly. But an attempt to install MS office 2010 was unsuccessful and only produced the error message shown:

"Setup cannot find the required setup controller file. Either there was a network error, and error reading from the CD, DVD, or other installation media, or a problem with the package you downloaded."

I tried various installation methods that did not help, these include: use of installation DVD, copying the installation setup from the DVD and running setup.exe, copying the DVD files onto a shared folder on a server and connecting to it, installing other versions of MS office 2010 (32-bit and 64-bit), and lastly copying the DVD as image and then mounting it in the Virtual Machine (VM).  Each of the methods applied to install MS office 2010 returned the same error message. The MS Office 2010 however installs and works well on a PC. Am I right in thinking the problem is a result of Parallels 7. Please help with a solution.
