My combine feature, after I have combined the files and hit the combine now key, gives me a notice that the feature needs a flash player. I have installed all updates. What’s wrong as I use this feature a lot.

Hi ​@Krbs4962@gmail.com,

Thanks for reaching out, and sorry about the trouble.
Flash Player has been deprecated for a long time; the application shouldn't prompt for it. This may appear when you open an old PDF file that depends on Flash Player.

Could you please provide a short video of the issue, so we can better understand it and provide an appropriate suggestion?
