Object does not get created on Virtual PC

I have set up a virtual PC (XP SP3) for executing automation developed in VBA. This automation creates an object of few Dlls developed in C# and VB.Net. But when I execute the automation using this VPC machine; the required objects does not get created and automation fails. 开发者_StackOverflow中文版Please let me know what could be the reasons for the same and how to troubleshoot the issue.

The Issue has been resolved. I required to run the windows update as some updated related to Office were not available on machine. Thanks.
