SQL 2012 sp1 CU1 PP for Excel File (32-bit)

I downloaded cumulative update #1 for SQL 2012 sp1.  I get an error unzipping the PowerPivot for Excel file for 32-bit. 

The file name is 2012_SP1_PPExcel_CU1_2765331_11_0_3321_x86 and can be downloaded from:

http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=2765331&kbln=en-us

I've downloaded it 3 or 4 times and on separate days but still get the error of "This self-extracting zip file is part of a multidisk zip file.  Please insert the last disk of the set."

I had a similar issue with the 64-bit Engine file which did get resolved yesterday.

Has anyone else had a problem with this file or gotten it to work?

Thanks,

Toni
