When I attempt to install Adobe Flash Player on my MacOS 10.13, I'll get to the final window that declares the installation is complete, but AFP app doesn't jump into my download folder. I'm ready to screen share with someone because I've already tried the adobe hotline and screen shared with someone that couldn't figure it out and online troubleshooting doesn't mention this problem.
No, nobody will call you, that’s not how it works. There is no support for free products. If anyone does call you, they are a scammer. Anyway... Flash Player is not an app. If it says the installation is complete, it probably is. Why do you feel it isn’t? There are many hurdles to make it deliberately difficult to run Flash today. You may need to enable it. What is your browser?
