Trouble authorizing ArcGIS 9.3 on windows 7

[LindseyKandiko]

I am having trouble re-authorizing ArcGIS 9.3 after updating my computer system. I can run through all of the registration pages and when I get to the final screen I get the error below:

Is this because ArcGIS 9.3 is no longer supported?

Is there any way I can put this system on my computer without buying the new version?

Thanks for the help

I've moved your post into the Enterprise GIS space. You will get a much better answer here as the GeoNet Help is intended for community help and feedback. I have also added in a few additional tags. You can see more on the community structure, and what topics are under each space from the following documents:
