Issue with Installing DotNet 4.8.x on Server 2019

[yerevan]

Hi,
I've read the previous threads about this issue, and have still been unable to install this. i've done sfc /scannow, the dism command to restore health, rebooted, etc. I still cannot install this install... i've tried the web version, offline version, and the KB itself: kb4486153

this is a requirement for QuickBooks 2023 to install. any help would be greatly appreciated.

thank you.

OK, i got this resolved on my own. I'll post here in case this helps anyone. Server 2019 latest patches as of August 2023. I could not install .net 4.8, this is an RDS server with IIS installed for RDS. We are trying to install quickbooks and 4.8.x is a requirement.

I was getting object not found errors as well as too many links errors. I ended up using this installation, but what really worked for me to resolve was going into server manager, clicking Manage at the top right, click remove server roles/features, and remove the .net 3.5 feature completely. I was unable to remove 4.7 as i believe IIS depended on it. So i only removed 3.5.

The server required a reboot. I rebooted. I then went into powershell after the reboot, and ran the following to install .net 3.5 and all features related to it...
Enable-WindowsOptionalFeature -Online -FeatureName "NetFx3" -All

I origianlly did not use "-All" and it threw an error suggesting i use -All.

After 3.5 re-installed via powershell command above, i was then able to quickly install 4.8.x per that link above.
