Can't Integrate 11.0.01 MSP into MSI Install

I created a custom install using the customization wizard, and have no trouble installing it using:

msiexec /i AdbeRdr11000_en_US.msi TRANSFORMS=AdbeRdr11000_en_US.mst /qb

Now I'm trying be able to install it with the 11.0.01 patch file included using:

msiexec /i AdbeRdr11000_en_US.msi PATCH=AdbeRdrUpd11001.msp TRANSFORMS=AdbeRdr11000_en_US.mst /qb

I get this error when I run that:

This patch package could not be opened. Verify that the patch package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer patch package.

Or when I add the full paths to the files:

msiexec /i "C:\Users\User\Desktop\AdbeRdr11000_en_US.msi" PATCH="C:\Users\User\Desktop\AdbeRdrUpd11001.msp" TRANSFORMS="C:\Users\User\Desktop\AdbeRdr11000_en_US.mst" /qb

I get:

The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the progpam to be upgraded exists on your computer and that you have the correct upgrade patch.

I'm installing it directly on a Windows 7 virtual machine. I did have Reader 9.5 installed, but I used the cleaner tool to remove it.

Thanks,

Bobby
