Error when running GUI as standalone!?

Hello!

I created a GUI on my notebook (Acer Aspire E1-572G), which i use to analyze data (FFT, etc.) stored on my harddrive (previously taken measurements) as well as collecting new data from a Picoscope 4824 USB Oscilloscope. When i run the GUI in MatLab everything works fine on my notebook. Now i created a standalone "exe"-file using the Application Compiler. It also works fine when i run this on my notebook. As soon as i switch the other notebook (Dell Latitude): Loading data from the harddrive or USB drive and analyzing it works fine, but when i try to connect to the Picoscope 4824, an error occurs:

Error using icdevice/connect <line 112>
An error occured while executing the drive connect code.
Unit not supported.

Here are a few things that i already tried/learned:

*) First guess: It has something to do with the USB connection / power supply. It is interesting that the Picoscope 4824 doesn't work in the "Picoscope 6" software either. A window with a "warning"/"info" about power supply pops up.

My notebook supports USB 3.0, the other notebook only 2.0 and i have to use the included "double-USB"-cable, where "Data" and "Power" are seperated. I used both USB 2.0 ports on the noebook, but it didn't work. I even tried to change the cables between the two USB ports, but it didn't work. So i tried to connect the "Power" cable to an external power USB-hub, didn't work.

Does anyone has any other suggestions regarding the USB connection or any other ideas what causes the error?

Best wishes, Georg

In the meantime i can meausure using the Picoscope 6 software. I'm not sure why, but it works! But using my .exe it still doesn't. Both notebooks have win 64 bit!
