I'm trying to prepare a deployment of office 2013 pro plus.

If I deploy an existing .rsp file that was left behind by the old analyst (typing from the client):

PS C:> \\deploybox\software\Office2013\setup.exe /adminfile \\deploybox\software\Office2013\SWKS.MSP

Things seem to deploy just fine.

if I make any changes to the .rsp file by doing (all from the client):

PS C:> \\deploybox\software\Office2013\setup.exe /admin

* Open SWKS.MSP
* Make changes
* Save under a different name SWKS1.MSP

I get the following errorbox:

Unhandled Exception:
MsiGetSummaryInformation call failed.

And if I try to deploy the new SWKS1.MSP,

PS C:> \\deploybox\software\Office2013\setup.exe /adminfile \\deploybox\software\Office2013\SWKS1.MSP

it fails with the message:

Path or file specified with /adminfile did not contain any customization patches that apply to this product or platform.

If I even open the old known good .rsp file SWKS.MSP, and immediately save it as a new name SWKS1.MSP, making no changes, then the same thing happens.

So what stupid newbie mistake am I making here?

Thanks!
