[3dem] remote microscopy question

[Zongli Li]

Hi David,

We have been using teamviewer to remote to both the support PC and Gatan PC
that runs Gatan GMS and serialEM. The connection is smooth without any
issue, as long as you have licence for using teamviewer. Of course our
PCs keep the original windows version. But I bet the teamviewer should
work with Windows 10.

Cheers,

Zongli
