Installing Zune software not going well

Earlier today I was flashing a friends Zune and the software stopped working. So I uninstalled it and downloaded the latest version. Now I get some error message every time I try to install it. The kicker is I've gotten about 5 different ones and none of the error codes Googled don't seem to turn up anything interesting. This is getting a bit frustrating... maybe I'll try installing the older version.

And I'd paste the error message here on the last one... but it doesn't let me copy the text. :( Here are all the error codes in just one message. 2203, 2147287035, 0x2, and another really long one that I don't even want to type in here.
