I have a computer game from the 80's and I want to install it on my dell notebook but the message saids" to find a version for your PC, check with the software publisher " I don't know what to do so the game will install

Software from the 80's won't run on Windows Vista or Windows 7 as they were not even on the drawing board when 80's software was written. Some 80's software won't even run on Windows XP. You need to buy an up-to-date version (if it exists) from the game publisher's website.
It would help to know the model of your Dell, which OS you're running, & the name of the game.
