Hi fixed-term.lukas.ebenstein@de.bosch.com,
You need to change the Matlab Add-ons installation folder because our VSDK doesn't support spaces in paths.
Open the Matlab Preferences windows and select Matlab -> Add-Ons page. There change the path to one without spaces in it. e.g.: C:\Users\xxxxxxx\AppData\Roaming\MathWorks\MATLABAdd-Ons. Notice the missing space character between 'MATLAB' and 'Add-Ons'.
You can rename the initial folder such that it doesn't contain spaces and update the path in the Matlab Preferences after. You must close the Matlab before renaming the add-ons installation folder.

After you change the add-ons installation folder, you need to reinstall the NXPVT Vision Toolbox.
Another thing I want to point out is that we didn't test our toolbox with VSDK 1.3.0 HF1 or HF2. We recommend you to use VSDK 1.3.0 release without hot fixes, HF1 and HF2.
