Hi,

you can't compile the toolbox that these functions are in "solve, syms, vpasolve". You should see this warning when you compile the app.

Hello,

To my understanding the error for permission occurs when you try to access a file for which you do not have permission to access or modify. I would recommand to check the file access settings from administrator.

Also, it looks like you are trying to complie a toolbox, which can not be done.

Please refer to the this answer for more insight.

Hope it helps.

Thanks for the anwser! Indeed the problem was that my folders are write-protected and so MATLAB compiler couldn't work properly.

To change the wirte protected properties of your folder didn't work for me somehow, dispite i am the administrator. Must be a new "feature" of win10...

The Solution is pretty simpel. Move the folder with your App to your Main drive root (C:) and the compiler will work.

Thanks for your repely! You saved me a lot of work !!
