How to Change TeamViewer ID after cloning

by Bruce on September 1, 2010

Update: The original post was for TeamViewer 6 (I think). The comments contain information on v7 and now also v8.

If you’ve cloned a machine that already has team viewer installed, the clone will have the same ID as the source machine.  Each machine needs it’s own unique ID.  To get the clone to pick up a new ID by deleting 2 registry keys, ClientIC and ClientID.

for 64 bit Windows 7 I found the key here…
for 32 bit Windows 7 the keys are here…

This won’t work on the source machine.  The calculation that determines the ID uses hardware identifiers which haven’t changed and TeamViewer will therefore produce the same ID as before.

I don’t yet know how to do it on a Mac.
