Something went wrong with the install.

You can troubleshoot the package failures by:

2. Modify your selections for the affected workloads or components and then retry the installation

Hello @Yicheng Zhou ,

Welcome to Microsoft Q&A forum.

Please try following:

1. Go to this C:\ProgramData\Microsoft\VisualStudio\Packages directory, and search "Microsoft.Net.4.8.FullRedist.20H2,version=4.8.9037.6" package. If it exists, please open this folder and check if there’s any .msi or .exe file, try to right-click them and run it/them as administrator(install manually).
2. Try to update Windows OS and install any pending updated Windows Updates in Settings > Windows Update.
3. Try to remove this folder("Microsoft.Net.4.8.FullRedist.20H2,version=4.8.9037.6") and continue/retry/repair installing VS.
4. Please try to download Microsoft .NET Framework 4.8 offline installer to install .NET Framework 4.8. If it installs successfully, please then reboot your machine and retry installing VS.
5. Please also make sure that you have enough permissions to install VS, and there’s no local group policy and limits. Please also try to disable antivirus software temporarily and retry installing VS.

Update1:

Here are some other suggestions that you can try:

1. Run CMD as administrator and run DISM.exe /Online /Cleanup-image /Restorehealth, after that run sfc /scannow command.
2. Try to reboot your machine and install VS again.

Feel free to let us know if any of above suggestions work.
