Please can someone help me with a bit of a dilemma on my side?

HI I got a new laptop and installed Movie Studio 16 Platinum from your website. It asked me for the activation code. I copy pasted the serial number into the  field. I got a message saying the serial number is incorrect. I then closed the program and wanted to reopen it. However, It's not installed.
I looked under programs and features. Also when I hit the windows key and type the word (Vega).
I can only see the Vega  exe file.

Can someone help me please. I don't just want to install it again. Also, I already did a reboot of my machine.
