Due to difficulties with sending emails, I decided to try a repair installation. After backing up all of my accounts, I tried to reinstall. I got the following error:

a network error occurred while trying to read from the file: C:\Temp\update.msi

I am trying to do the install using the downloaded file C:\Temp\zdesktop_7_2_2_ga_b11951_20130318071431_wi n32.msi

I'm not quite sure how to address this issue. Any help would be appreciated.
