Imtool not working?

I just type in imtool and run it, for some reason I get an error, there is no other code running. Why could this be happening?

Well since you're not supplying the actual error message and asking us to make a "blind" guess, about all I can suggest is that you don't have the Image Processing Toolbox installed.

It was only saying 'error imtool' but it's somehow working now and I haven't changed anything, all I've been doing is typing imtool into the command window.

You need to include the image name in order to display it, like

imtool('board.tif')

Or you can use just imtool() and then use "File->Open..." from imtool's pulldown menu to load an image. Either way assumes that imtool can launch in the first place.
