This procedure will enable you to save the installer log which can then be attached to a support ticket that you can create at https://eareview.net/support
Assuming you already downloaded the installer and it is located in your Downloads folder:
1. Start a command prompt. If unsure how, you can click the Start menu, type 'cmd' (without the quotes) and press Enter.
2. Type
%USERPROFILE%\Downloads\tds2-setup-v2.2.X.0.exe /L*V %USERPROFILE%\Desktop\tds2-install.log
Be sure to replace the X with the installer version you downloaded. For example, if you downloaded v2.2.36, the line you would have to execute would be:
%USERPROFILE%\Downloads\tds2-setup-v2.2.36.0.exe /L*V %USERPROFILE%\Desktop\tds2-install.log
3. Go through the install procedure until the installer finishes (or an error comes up) then exit the installer.
4. You will find a file named tds2-install.log on your desktop which contains the installation log. That is the file you need to send.
