There is a link at Adobe help support for a Shockwave version,
but not sure if that's something that is actually anything good.

'Shockwave 10.2.4.194' seems to be most current
~ but that does not mean it is up-to-date or secure.
Be sure to use the official Adobe support sites
for anything of their brand and avoid others who
may be adware hosting or malware laden frauds.
IF in doubt, use the Adobe sourced 'uninstaller' to
be rid of an older or somewhat suspicious product;
also check for adware if odd symptoms arise after
an installation if a browser window prompted you to
get Flash from in a browser; not from Adobe/direct.
{Could be the Shockwave isn't really installed; in a
newer Mac OS X there are security measures to
keep certain applications from installing. Unless it
is temporarily disabled, GateKeeper may disallow.
See Adobe Help linked below to check for installed
Adobe flash and shockwave product versions.}
As for me, I don't use Adobe Flash or Shockwave.
For the most part, across several Mac OS, Adobe
is not a popular item for me; I doubt their security.
When faced with Flash or Shockwave, I've referred
to their own Help pages for ideas.

by someone in Adobe software; Preview may not show
all details an author may have included, otherwise.}
Good luck in this matter! 🙂
