One of my users has an XPS13 out of warranty running Windows 8.1. He made a mistake and downloaded the trial of Adobe Acrobat DC.  It uninstalled the Acrobat 11 that we got bundled with the computer. No problem, says I.  Uninstall DC and use Digital Deliver to re-download 11.  Hah! There is no Dell Digital Delivery shortcut anywhere.  There is a folder in Program Files (x86) but none of the executables do anything.  The service is running. So in Programs and Features I try "Repair".  It wants the CD. OK, I find where to download Dell Digital Delivery from the Dell web site. Repair won't accept the MSI as a repair source. Next I run the MSI and it informs me "account already exists" and quits. So I uninstall DDD from Programs and Features.  Now I run the DDD MSI and it tells me that a newer version is already installed and must be uninstalled first. AAAAAARRRRRRGGGGGHHHHHH!
Can't re-download... no Digital Delivery
