Hi All,

Just in case someone else gets this same problem. I found the following solution (unfortunately without any real support from Stardock):

The copy/paste problem with Multiplicity Pro kept bugging me so I did a little debugging and ran Sysinternals Procmon on Multipl.exe on both secondary and primary computers. In the copy/paste operation from primary to secondary I found Multipl.exe had a filename collision error on the secondary computer with "C:\Program Data\Multiplicity Temp". I deleted the zero size file and lo and behold, everything now works as it should.
Surprised this issue hasn't come up before. Looks like the file "Multiplicity Temp" is supposed to be deleted by Multiplicity after each copy/paste, but for some reason it wasn't on the secondary and thus the problem. 

Hope this helps future troubleshooting sessions.

Regards,

I'm having the same issue here with my setup.  Copy & Paste isn't working but everything else is.  I've tried deleting the files in C:\Program Data\Multiplicity Temp and that doesn't help.  I've opened the ports, 30564 and 30565 and that doesn't work.  Even disabling Windows Firewall on both PC's doesn't work.

It's copying from the slave to the master but not the other way round.  It's really annoying becuase I'm so used to it and I can't live without it

Yes, they have emailed but they haven't given any sort of answers, just questions about my setup.  No reply in over 48hrs.

If everything was working previously then it points to something changing on your setup.

For copying from the primary to secondary the primary must have port 30565 open on it.  For secondary->primary it would be the same port but on the secondary.

Typically not being able to copy one way would point to a firewall blocking it on one of the ends which will be the end you are copying from.

Was this ever fixed as it's sort of a deal breaker for me.

This thread relates to MP 1.x and the clipboard code was changed completely in later versions.

If you ever find clipboard only works one way, it means the firewall on the computer which has the clipboard contents is blocking Multiplicity.  This can happen with third party firewalls which do not use the OS firewall rules which Multiplicity will have setup.

Also if one computer believes it is on a public network vs a home/work network it will have the firewall blocking Multiplicity as Multiplicity rules are only set to be open when on a trusted network (for added security).  Occasionally a computer can set itself to public in error.
