I had something like this in my last job: I had to create an installer for a VCS aimed at chip designer. The installer would be ignored as much as my coworkers could manage, and as many customers as possible had to be able to just use it unmodified. Since our supported OSes were RHEL6, RHEL7, SLES12, and SLES15, the best option was bash. Also had to build it on the off chance one of our more restrictive customers was still on RHEL5.11 Pain in the butt, but it worked.
