Hi guys, I'm trying to uninstall the "Mapping toolbox" but I get the following error in the "product uninstaller" window:

" The application encountered an unexpected error and needs to close. You may want to try re-installing your product(s). More information can be found at C:\Users\peppe\AppData\Local\Temp\mathworks_peppe.log "

Here a part of text on the .log file:
