To install the Image Processing vis, follow the following steps:
1. download the library here
2. unzip the library
3. move the library into your "Labview:vi.lib:user.lib" folder (look in the Applications folder on the mac and the Program Files on the PC).
4. open LabVIEW
5. make sure to save all changes when it recompiles the library for your operating system.
note: for some reason, some people, when installing, will end up with a broken arrow and not be able to run a number of the vis. This is because the lowest level QT vi has lost the connection to the lsb (driver) file. This can be fixed by going down to the lowest level - and one of the vis will say QT_Call_Win or QT_Call_Mac - that diagram has a code interface node - you need to reload the file. Right btw click on the node (top) and select "Reload Code Interface From..." and then select the right library (it is in the Image Processing : QTLIB_2595_LV86 : CINWin.lsb or QTLV_x86.lsb) and save all changes.
