I can use serum demo help me

I can't download serum demo? Help me and it won't open

Hi,
The demo installs the VST (+AU / AAX) Plugin which is loaded from within your music making software. You could try searching the web e.g. "using VST instruments in X" where X is your music making software (DAW). Please mention your DAW and OS (and a bit more description, if possible) if you are still stuck.
