I created a VM with a Win10 install quickly, and performed the following tasks to get Win32::MultiMedia::Joystick to seemingly work (well, it doesn't complain about missing modules or brokenness). I use berrybrew here, as it allows you to keep separate your system Perl, and allows you to remove an installation if it breaks, and re-install at will.

• download/extract berrybrew.zip somewhere (not c:\berrybrew)
• open a cmd window
• cd berrybrew
• bin\berrybrew.exe config (type 'y' when asked)
• close the current cmd window and open a new one
• berrybrew install 5.24.0_64
• berrybrew switch 5.24.0_64
• close cmd window, open a new one
• cpanm Win32::MultiMedia::Joystick

Then, on the command line:

perl -MWin32::MultiMedia::Joystick -e ''

You shouldn't get any errors. Attempt running your script on the command line at this point and see what happens.

To go back to using your (possibly broken) system Perl, just do berrybrew off.
