Hi rejohnson76,

If you are just looking to extract the files, you will have to run the setup.exe with the following parameters:
/extract_all: Extract all contents of the MUP

I found this into in a similar thread on the Dell Support forum
http://en.community.dell.com/support-forums/laptop/f/3518/p/19406316/19948214.aspx

Unfortunately, those parameters only work for driver MUPs, not applicaton MUPs. I still need the command line to extract application MUPs, such as R303961. Thanks.

This is how I was able to extract the contents of the Update package to get an MSI file.

1. download the package for R303961 from support.dell.com
2. browse to the download directory and extract the contents using Winzip or from a command line, type "APP_WIN_R303961 /s /e=c:\temp"
3. go to the directory you extracted files to and will see a setup.exe
4. from a command line run "setup.exe /v/x"
5. the contents of the package will be extracted to "C:\Windows\Downloaded Installations" where you will find a subdirectory that contains the file called "Dell Mobile Broadband Utility.msi"

i think that's all you want.... but If you want to extract the MSI file use the command line
"msiexec /a "dell mobile broadband utility.msi" /qb TARGETDIR=c:\R303961"
