Part 8: Frequently Asked Questions (FAQ) Q1: Is .NET Framework 4.8.1 the same as .NET 6.0 or .NET 8.0? No. The classic .NET Framework (4.8.1) is Windows-only and ships with Windows. .NET 6/8 (formerly .NET Core) is cross-platform (Windows, Linux, macOS). They are side-by-side products. You may need both installed. Q2: Can I uninstall .NET Framework 4.8.1 and go back to 4.8? Technically yes, via "Add/Remove Programs" → "Turn Windows features on or off" → unchecking 4.8.1, but Microsoft does not recommend it . Applications built against 4.8.1 may break. System Restore is the safer revert method. Q3: Why does the offline installer sometimes require an internet connection after launching? Even the offline installer checks for revocation of digital signatures (CRL checking) and may download language packs if you chose a non-English base installer. To make it fully offline, run it with the command line flag: NDP481-x86-x64-AllOS-ENU.exe /DisableCRLCheck Q4: How do I verify that .NET 4.8.1 installed successfully? Open Registry Editor and navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full Look for the Release DWORD . For 4.8.1, the value should be 533320 or higher (for newer builds).
