Changing Multiplicity Ports 

These are the keys you will need to add \ edit. PLEASE back up what you have now prior to changing anything. These are examples are for 64-bit machines.

Primary - controlling other machines

WinKey + R, regedit, enter.  Navigate to the following using the name of the Secondary machine you want to connect to; SDROHAN-TEST is the Secondary MP machine in this example

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Stardock\Multiplicity2\Machines\SDROHAN-TEST]

"Name"="SDROHAN-TEST"

"DisplayName"="SDROHAN-TEST"

"DynamicIP"="1"

"Address"="10.8.15.109"

"Passkey"="1101"

"LastWorking"="10.8.15.109"

"Port"="17"

Note the addition of the string value Port=17. You can choose what ever port you like here (excluding the know commonly used ones of course). 

Primary - what itself uses

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Stardock\Multiplicity2\Security]

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Stardock\Multiplicity2\Security\Ports]

"OverridePort"="1"

"OverridePortPort"="17"

"OverridePortPort2"="55"

OverridePortPort2 is the clipboard port. Again, use any port you like here.

Secondary

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Stardock\Multiplicity2\Security]

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Stardock\Multiplicity2\Security\Ports]

"AllowNonRoute"="1"

"OverridePort"="1"

"OverridePortPort"="17"

"OverridePortPort2"="55"

OverridePortPort2 is the clipboard port. Again, use any port you like here. 

Running a command prompt as admin and netstat -a will show that it is now listening on the new ports
