Software is requiring Acrobat Reader 9 but we have Reader DC

[Tor23929035i3xe]

We have industry specific software which is requiring Acrobat Reader 9.  The install file installs Reader v9.3.  We have been running Acrobat Reader DC, which I feel comfortable with.  Reader 9 is out dated and I don't feel safe running it.  Is there a way that I can put a "redirect" (or something else) to trick the software into using DC?  I have put in a formal complaint with the vendor as v9 is no longer supported by Adobe, and hasn't been since 2013.  Thank you in advance.

If the app is somehow checking for Reader 9, and specifically rejecting later versions, it probably has a reason; probably it uses a feature that was removed or changed. Maybe it requires a plug-in that Adobe no longer allow. We can't really guess. Anyway, trying to trick it, is likely to hit whatever the reason is that they put the check in.

If the app is old and just bundles this old Reader, you may be able to bypass that part of the install.

Thanks.  It seems to need something specific in v9.  I can uninstall 9 after it's installed.  I'd love to update the path to the starting file for Reader, but I don't know how.  I asked them and they said I can't do that and that it needs 9.

This is a related question:  Am I correct in thinking it is unsafe to run Reader 9?  There is a site that says it has 137 currently known vulnerabilities, most of which are 10/10 on the "severity scale".

Just open the PDF file directly in Reader DC. I'm willing to bet it will work just fine.
