That is just the update. That's the one I ran to update the 10.1 to 10.1.1.
Notice the normal install is 150mb and this is only 50mb.
Sorry, I didn't spot that. Hope I didn't waste your time.
It looks to me as if the update hasn't been tagged on to the original installation. Here's the download link for all of them: http://www.adobe.com/support/downloads/product.jsp?platform=windows&product=10
The only tools I can find are these: http://www.adobe.com/products/acrobat/technical-resources.html#documentation-guides but you probably have them already.
Maybe one of the other contributors might be able to suggest an alternative method of achieving your goal.
