TeamViewer 5 Setup Installer Corrupted: Invalid opcode
It seems that the exe file is corrupted by the w32 virus that is why it causes this error. It is better to use the latest version of team viewer software. I will provide you the URL address to download it.
Dear Davis Avon,
It is preferred that you download the file again from this URL:
After you have downloaded the file, close any open browsers and run the install as the administrator to prevent any error that can occur after installing.
Restart the PC after the install is complete.
Hope that this was helpful
