ScourgeOfWar-Update-v101.exe ERROR

[Waffenmuffin]

I just purchased and installed the Quatre Bras and Ligny DLCs. My installation of Waterloo had already been updated to v1.01 with all prior updates. I'm using Windows 7 64 Ultimate. When I went to install Quatre Bras I got a message that said I needed to update Waterloo. During that update I got a message that Waterloo "Patch 3" cannot install because there isn't enough disk space. I have 2.27tb free on my HD. Both DLCs appear in the DLC subfolder but neither appears as tabs next to the Waterloo scenarios tab. I've read the other posts about problems getting the DLCs to run but have not seen a solution to the not enough disk space error. I've also tried to run ScourgeOfWar-Update-v101.exe as administrator but received the same error. Otherwise the game appears to run properly. Any ideas? Thanks.
