Flash player required accessing my military personnel file

Hi, I recently received my personnel file from my time of military service and it came in disc form requiring me to have adobe flash player on my adobe reader. I have a windows 11 acer laptop that does not have flash player already on it so I can't view my records at the moment due to flash player being blocked and removed from your site. I really need flash player. It's so I can view my records and get my medical benefits due to the exposures I had in Afghanistan. I understand that this is an inconvenience for you guys but this is a major inconvenience for me as well. I'm hoping to  even purchase a copy if possible
