[Invalid ChartFX License 3100000]

Uninstalling & reinstalling didn't help. I still get the error.  I didn't reboot during the process, maybe I should?  I've noticed that when I uninstall .NET 6.2, it is still in the registry under WOW6432node.  I don't see it under the hkey_local_machine/software/software fx, but i do see it under hkey_local_machine/software/wow6432node when it's uninstalled.  All the .Net 6.2 stuff are still located under wow6432node even though I uninstalled the product...Will I need to reboot?  I feel like it caches something in the registry that keeps giving me the error.  Could this be an issue?

 Thanks in advance & for helping out...

Thanks.  I did check the version we currently have.  We got chartfx a few years back.  Current version of the installer is:6.2.2211.19403 & the latest installer I see is 6.2.3188.26800.  Will there be a licensing issue in regard to different versions?

I was researching online, but only found that this may be related to chartfx .NET 6.2.

 I got chartfx 6.2 installed & a valid license, but I get the error "InvalidChartFX License 3100000" on a webpage where the chart should be.  I'm not sure what could be causing this...I read some instances where this could be a Service Pack issue.  We have a service pack installed, but I'm not sure what this can be.
