I cannot install Team Viewer on New Dell PC running latest version of Windows 10. I get the following message.
Error opening file for writing:
C:\Program Files (x86)\TeamViewer\TVExtractTemp\tvfilesx64.7z
Is the account that you are using a Administrator account? It could be the problem that you have not the right to open the file's. Could you check that for me please?
I hope this helps,
Thank you for using teamviewer!
