Bash: /home/Owner/mrtrix3/bin/mrview: Permission denied

why do I suddenly get this message?

Can anyone tell me please?

The programme was working fine till yesterday

but I suddenly get this message when I execute mrview

Hi, this is most likely due to a system update. Try restarting your computer – that should be enough to fix it. If not, run ./build clean and ./build to recompile.

Thank you

Maybe I should try the method you’ve told me next time

I just reinstalled the programme before I checked your reply
