Office 2007 Fails to install AMD64, Citrix PS4x64

[Dharitree]

Facing a error on Office 2007 while activating it through Volume License key. The error says about product installation failure. I had tried to roll back to the older edition but somehow it does not worked. I am using a system running on Citrix PS4 x64. I hope this would not be so complicated to install. There must be some way to fix the issue. I had added a patch to the system.

There are number of causes behind the error. You must restart your system and try to configure the setup one more time. I am sure this would help you in fixing the issue. Second ensure that for sometime there is no updates are installed. Because this new are still pending to take affect until your system is not restarted. If you have more than one Office installation CD, then try with other one.
