I attempted an update yesterday and probably didn't pay attention do all the dialogues I just assumed it worked. But after I was not able to launch ZD client. I'd see a little window flash and then close almost instantly, even after reboot.
I downloaded the full client and attempted to repair install but I get this error
a network error occured while attempting to read from the file: C:/update.msi
The path will differ depending where you try to install from, originally I was installing from desktop then I moved the zdesktop_7_2_1_ga_b11637_20120906071254_win32.msi
to c: to see if that would help but it did not... any ideas? I have disabled antivirus with no difference as well.
