I am trying to create an AIP to roll out adobe rdr X via GP.

I have downloaded via AdbeRdr1010_en_US.msi and AdbeRdrUpd1012.msp, and then used the command:
msiexec /p AdbeRdrUpd1012.msp /a AdbeRdr1010_en_US.msi
to create an AIP.

I also used the Adobe Customisation tool to create an mst for EULA, silent install etc. (I copied a setup.ini from an expanded exe version)

On attempting to deploy on windows 7 I'm getting:
Product: Adobe Reader X (10.1.2) -- Error 1334.The file 'adobearmhelper.exe' cannot be installed because the file cannot be found in cabinet file 'Data1.cab'. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package.

I have tried an number of things, e.g. right clicking the msi to install and still get the same result.

Any ideas?
