Pack and go Missing.

I am having issued with the "Pack and Go" Option in windows explorer. I will give you some backgroudn information on my machine:

I recently upgraded to 2011 Solidworks Professional X64 SP4.0.

My previous version was 2009 SP0.0

I have windows 7 Professional and a 64bit Operating System.

The Issue I am having is the "Pack and go" option is missing from Windows Explorer. I can pack and go from every other venue (Solidworks explorer, in Solidworks itself). I am wondering if anyone else has experienced this issue and if anyone knows any way to fix it.

I am attaching a picture whichs shows where I am trying to use pack and go but it is missing.

Thank you,

Russell
