Windows 7 ultimate SP1 Error downloading .net 4.8

Recommended Posts

Hi People,

Just joined up and bought the lifetime license, great product.
After trying to configure hyperspin for about 4 years, Your Launchbox/Bigbox is a godsend.


I installed on my windows 10 PC to test and worked fine.

My arcade machine is running Windows 7 Ultimate SP1 but will not install .net Framework 4.8 through the installer or manually.
Error: a certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.

I would like to run it on WIndows 7 if i can as it will not be on the internet and doesn't require updates every week. 


Has anyone else come across this problem?

Fixed it.
For anyone with the same issue, I had to go into uninstall programs - windows components - then untick windows media centre under the media container.

Download and install Visual C++ 2015 then 2017 then 2019

Now it boots! :)
