When creating your own custom Toolbars you may want to find or create some button faces.
In AD17 Button Faces can be Found at:
C:\Program Files (x86)\Altium\AD17\System\Buttons
After upgrading from AD13 to AD14 my custom toolbar which I created in AD13 was missing.
To restore my custom toolbar in AD14, I copied the following three files from AD13 :
DXP.RAF
DXP.RCS
UserTools.TLT
AD13 Location:
"C:\Users\Your User Name \AppData\Roaming\Altium\AD {xxx . . .}"
AD14 Location:
"C:\Users\Your User Name \AppData\Roaming\Altium\Altium Designer {xxx . . .}"
Tip: Altium must be closed while you copy the files, because the files are over written when a session of Altium is closed.
Just to be safe create copies of the AD14 files before overwriting them.
Refer to Link: Altium Forum Search:
C:\Users\username\AppData\Roaming\AD {<GUID>}
Where GUID is a long Set of Hex characters.
Use File Search if needed to locate the files shown below on your computer.
Copy the following files and paste it to the same location on your new PC.
DXP.RAF
DXP.RCS
UserTools.TLT
Altium has to be closed, during this precedure, or else your copied files will be overwritten.
These files are overwritten when Altium is Closed.
If you are frequently updating your Toolbars, then Synctoy can be used to simplify this task.
