HiWhich version can I use?This is not normal windows 7.Here's a more detailed description: https://www.microsoft.com/windowsembedded/en-us/windows-embedded-compact-7.aspx
I tried it. An error message. Not compatible. Pride what would be good?
Most TeamViewer versions should still work on that system. I've personally used 6 and 10 on embedded versions of Windows. If you can use 13, you probably should, but you shouldn't run into any issues that I know of with other versions.
