CAT12 Toolbox Won't Launch and Displaying an Error Message

I have downloaded SPM12 and unzipped and installed cat12 in the spm12 toolbox folder. This shows up but when I try to press on it to launch CAT12 I receive the following error:

SPM present working directory:

/rds/projects/f/farrowe-prescient-eeg-analysis/MRI/Dechante/spm12

Error using spm('TBlaunch',get(gcbo,'UserData'),get(gcbo,'Value')-1), set(gcbo,'Value',1)

Invalid use of operator.

Error in spm (line 954)

evalin('base',xTB(i).prog);

Error while evaluating UIControl Callback.

If anyone could help me I would really appreciate it
