Click on 'Config' on the rtl1090 screen.
Do you have the port set correctly?

Edit: Did the driver install correctly? Does any other software find the dongle?
Zadig - USB driver installation made easy
When the Zadig driver is properly installed, it will show in your device manager as shown below.
Bulk-In, Interface (Interface 1)
If Windows installed the default driver, you'll have to delete the device in 'Device Manager', reboot, and start over.
The default driver is NOT good for your purposes.
I installed the driver on all of my computers quite a while ago, so some things may be somewhat different now.

If you are running Windows 8 or Windows 10, you can read this.
"Solving issues with device drivers and programs in Windows 10
"If you want to plug some old or specific hardware and the Windows drivers are not signed, you might need to disable the driver signature enforcement in Windows 10 (or Windows 8/8.1) because Windows will not allow you to install those unsigned drivers. The typical solution is to reboot Windows into Advanced Startup mode and disable driver signature enforcement."

I just followed the instructions via Command Prompt and dongle still doesn't show via RTL1090. Not sure what is causing the issue and I don't know anyone close by to come over and fix the issue.
Does it show in device manager with the correct driver?
If so, then it may be a setup problem with rtl1090.
Have you tried it with SDRSharp or some other software?
If not, I could send a zip file to you that contains a working copy of SDR3.
You just unzip it into a separate folder and run it to verify the driver is installed correctly.

Under device manager it shows the right driver. I haven't tried it with anything else. Could you send me SDR3?
Sure can.
PM me a good email address that can receive a 1.5mb file and you'll have it shortly.
Just unzip the contents into is own folder and start the SDRSharp application.
If the driver and dongle is good it will start running, tuned to the middle of the NOAA 162 MHz Weather band.

You should really be using DUMP1090 as it provides raw data for MLAT.
I got DUMP1090 running but its not picking up any aircraft...So I guess no aircraft near by? What settings do I need to use?
It sounds like your computer still isn't recognizing your device. Are you sure you got the drivers all set up?
What kind of antenna are you using?
