My teamviwer recently begane giving me an error message everytime I opened it saying that one or more files had been modified or were missing. I uninstalled the program and when I try to reinstall it, I am given an error message that reads "An error occued during the installation.Installation aborted!". The last action I see on the progress bar before the error message pops up is "copying files". Any idea what the problem and solution may be? I'm running windows 7 professional and I'm running the install as an administrator.
