Toolbox no longer available and Installation path not accessible

I installed by ".mtbx" and used an toolbox. It worked fine, but i changed the user folder name on my windows system. Now when i try to use function from this toolbox, i have this issue "Unrecognized function or variable" and i can't reinstall this toolbox beacause "Toolbox cannot be installed. Installation path is not accessible".

How can i fix it without reinstall Mathlab ?

I use the 9.8.0.1323502 (R2020a) Matlab version with COVID-19 Classroom Access trial and this toolbox https://petercorke.com/toolboxes/robotics-toolbox/

[Walter Roberson]

which operating system? The paths are different for the different operating systems

[Walter Roberson]

for that matter I just suggest that you use pathtool to locate the current path entries for the toolbox and remove them, and to add in new entries reflecting the new locations.

Hi,

I had the exact same problem. I also changed my user folder name and I could not install a .mtbx toolbox afterwards (actually the same tool box as you) although I've had the tool box installed before I changed user folder name.

I tried to reinstall MATLAB but it did not work.

The solution I found was to run MATLAB as administrator which gave MATLAB write access to the path and to install the tool box.
