SUMMARY

This step-by-step article describes how to troubleshoot issues that you may experience when you install the .NET Framework 1.1.

When Microsoft Windows Installer is incorrectly registered in the Windows registry, the .NET Framework 1.1 Setup program cannot gain access to some Windows Installer components. This article discusses how to work around this issue by unregistering and then reregistering Windows Installer.

You may not always be able to completely remove the .NET Framework 1.1 by using the Add/Remove Programs tool in Control Panel. This article also discusses how to work around this issue either by manually removing the .NET Framework 1.1 from your computer and then reinstalling the .NET Framework 1.1, or by repairing the .NET Framework 1.1.

  • Microsoft .NET Framework 1.1
  • Registry Editor
