Unable to upgrade to v10

[lillars]

I have Team Viewer (free license) installed for unattended access on at least seven different computers. They all run Windows 7 or 8 64bit.
All of my computers have happily upgraded to TV v10, except one. The computer I sit at the most (Windows 7 64 bit), and use to access all the other computers, will not upgrade to v10. When I click the arrow to check for updates I get a message that says "An error occurred while updating Team Viewer. Please check log file for more information."
This is what the log file shows:

I see the error code "12150" and have searched on Team Viewer support, and the forums here, but I have not found anything relating to that error code. So, I have tried a few standard things. I have gone to the TV site and directly downloaded v10. The download happens fine, but the install will not run at all. I uninstalled TV completely, rebooted my machine, and downloaded v10 again, but the install still would not run. I shut off all firewalls and anti-virus, rebooted and tried again. Still the install would not run. I am able to uninstall and reinstall v9 as many times as I please, but I cannot access the other computers until I get this one upgraded to v10. So, I was hoping one of you super smart peoples could help me out, please.

Open your explorer and type in "%TEMP%\TeamViewer" into the address bar (without the ""). Can you access that? If so there should be a TV10Install.log file that may have more info on what's going wrong. If you can't access the folder or the file is missing, check the permissions for it and for %TEMP%.

Any ideas?

Did the other person eventually upgrade successfully?

not sure if this was answered somewhere else, but came across as 1st result for the issue and got mine working, so looking out. and all i did was turn my vpn off to download, i assume a proxy would have the same affect. I am not sure what is technicality causing it, but if you have a vpn or proxy try and download with it off.
