Hello vpanzitta and welcome to the community! 

Thanks for asking here and let me help you on this matter.

There are 2 reasons you got the Invalid serial number error, 1st is you downloaded and installed the wrong program, 2nd is you typed the serial number incorrectly. 

You can follow the steps below on how we can resolve the issue. 
Step 1: Look for your active serial number. Click here to see several ways on how you can find it. 
Step 2: Download, install and activate the correct program: 
- Click here if your serial number starts with letter X.
- Click here if your serial number starts with letter P.
- Click here if your serial number starts with letter A
Note: Make sure to follow the steps on the link carefully. 

Step 3: If the issue still persist, try to delete this file from your computer: corridor.dat
File location: C:\Program Data\Trend Micro\corridor\corridor.dat

Step 4: If the same error appears, take a screen shot of it, set this thread into private, and provide all the needed details below: 
Serial number: 
Order number (Online purchase):
Date of purchase: 
Picture/Copy of Invoice (Retail Purchase): 

I hope this helps. 

Thank you and have a great weekend!
