TortoiseSVN has its own program (TortoiseMerge) to show the differences between two different versions of a file. This works well with text files but since LabVIEW VIs are binary files it is advantageous to use LabVIEW's graphical differencing capabilities.
The professional version of LabVIEW has a "CMP Compare two VIs.vi" in the ...\LabVIEW x.x\project\procmphier.llb library.
The open-source "LVDiff" tool (see [1] for the main download but download the updated "lvdiff.vi" from the link here [2] since the version currently in the .zip file does not work with VIs in libraries) provides a wrapper to call this VI.
Configure TortoiseSVN to use LVDiff for VIs
Open Windows Explorer.
Right-click on a directory and select "TortoiseSVN...Settings" from the pop-up menu.
Under "External Programs" select "Diff Viewer".
