How can i change the path for C:\Program​Data\MATLA​B\SupportP​ackages\R2​017a\3P.in​strset\ev3​javahidapi​.instrset\​javahidapi​\hidapi-1.​1.jar to my D:\Program​Data\MATLA​B\...?

I'm working with EV3 Support Package with Simulink. When I'm doing: h = legoev3('usb') this shows

Warning: Invalid file or directory 'C:\ProgramData\MATLAB\SupportPackages\R2017a\3P.instrset\ev3javahidapi.instrset\javahidapi\hidapi-1.1.jar'.

In realtime.internal.CommUSB (line 20)
In legoev3 (line 304) 
Error using legoev3 (line 307)
Failed to connect to EV3 through USB. Please check your USB connection.

I know it is not the connection with the EV3, but it is a path error with the folder and I need to change it to my 'D' drive. I have already change the path for this:

>> realtime.internal.getEV3IORoot

ans = 'D:\ProgramData\MATLAB\SupportPackages\R2017a\toolbox\realtime\targets\ev3io'

>> matlabshared.supportpkg.getSupportPackageRoot

ans = 'D:\ProgramData\MATLAB\SupportPackages\R2017a'

But everytime I run h=legoev3('usb') seems like it didn't change and looks in the C: drive folder.

Also I change the Environment Variable - Path.

From: C:\ProgramData\MATLAB\SupportPackages\R2017a\3P.instrset\ev3sourcerylite.instrset\CodeSourcery\bin

To: D:\ProgramData\MATLAB\SupportPackages\R2017a\3P.instrset\ev3sourcerylite.instrset\CodeSourcery\bin

I know that i might move all to the C drive but i do not have enough memory so i need to work in D drive.

Anyone know how to solve this error with paths?

For now I copy the Support Packages Folder from D to C drive and its working, but still not find the solution to referencing the folder in the D drive.

I would probably use a symbolic link; https://en.wikipedia.org/wiki/NTFS_symbolic_link

Any answer to this important question? We would like to install Matlab on SSD and keep everything on SSD.
