While attempting to install Logos, you received the following error:
"Installation of Microsoft .NET Framework did not succeed."

OR: You were directed here by a Logos Technician.

Problem:

This error occurs when Microsoft's .NET Framework is unable to be installed or updated, usually due to a corrupt file or setting in a previously installed version of the Framework.
Logos Bible Software requires the Microsoft .NET Framework, which is developed, serviced and supported by Microsoft, so issues with .NET may prevent Logos from installing or operating correctly. For your convenience, we have collected some of Microsoft's basic troubleshooting steps below.

If these steps do not resolve the issue, please contact Microsoft for further assistance with this issue.

Solution 1: Repairing .NET

Microsoft recommends using these steps to repair problems in the .NET Framework before attempting any further troubleshooting.

.NET 4.5 (Windows Vista or higher, Required for Logos 5)
  • Open the Control Panel.
  • Click on "Programs".
  • Choose "Uninstall a program".
  • Locate "Microsoft .NET Framework 4.5" in the list; there may be multiple entries.
  • Select the highest version present.
  • Click "Uninstall/Change".
  • When the .NET Installer opens, choose "Repair".
  • Repeat these steps for all versions, highest to lowest.

Note: .NET Framework 4.5 is included as a "feature" in Windows 8 and cannot be removed. It can be "turned off" in the "Turn Windows Features On or Off" side-menu, then turned back on after restarting the computer.

.NET 3.5 (Windows XP, Required for Logos 4)
  • Open the Control Panel.
  • Click on "Add or Remove Programs".
  • Locate "Microsoft .NET Framework 3.5" in the list; there may be multiple entries.
  • Select the highest version present.
  • Click "Uninstall/Change".
  • When the .NET Installer opens, choose "Repair".
  • Repeat these steps for all versions, highest to lowest.

Retry the Logos installation to see if this repaired the issue. If it did not, or you received an error, proceed to Solution 2.

Solution 2A: Uninstalling .NET

If the repair function did not fix the issue, Microsoft recommends reinstalling .NET Framework. It is recommended to start with the highest version currently installed and work your way backward to .NET Framework 1.x.

.NET 4.5.1 (Windows Vista or higher, Required for Logos 5)
  • Open the Control Panel.
  • Click on "Programs".
  • Choose "Uninstall a program".
  • Locate "Microsoft .NET Framework 4.5" in the list; there may be multiple entries.
  • Select the highest version present.
  • Click "Uninstall/Change".
  • When the .NET Installer opens, choose "Remove".
  • Repeat these steps for all versions, highest to lowest.

Note: .NET Framework 3.5 is included as a "feature" in Windows 7 and cannot be removed. It can be "turned off" in the "Turn Windows Features On or Off" side-menu, then turned back on after restarting the computer.

.NET 3.5 (Windows XP, Required for Logos 4)
  • Open the Control Panel.
  • Click on "Add or Remove Programs".
  • Locate "Microsoft .NET Framework 3.5" in the list; there may be multiple entries.
  • Select the highest version present.
  • Click "Uninstall/Change".
  • When the .NET Installer opens, choose "Remove".
  • Repeat these steps for all versions, highest to lowest.

Solution 2B: Reinstalling .NET

You can reinstall .NET Framework in 2 simple steps:

You can now retry your Logos 5 or Logos 4 installation. If you were updating, restart Logos to restart the update.

Solution 3: Using the .NET Cleanup Tool

We have found that the official Microsoft instructions (Steps 1-2) do not always resolve .NET issues, but the following steps have proven effective in most cases. These are not official steps provided by Microsoft, but they are developed and maintained by Aaron Stebner, who helped develop .NET Framework 1.x-3.5. Use at your own risk.

    Using the .NET Cleanup Tool
  • Download the .NET Cleanup Tool from Aaron's blog.
  • Open the Zip file and copy the "cleanup_tool.exe" to your Desktop.
  • Open "cleanup_tool.exe" and accept the user agreement.
  • Select "Cleanup All Versions" (default) and click "Cleanup Now".
      This takes a while, but may appear to be frozen for several minutes. Please do not interrupt the process.

If cleanup is successful, restart the computer and reinstall .NET using the instructions in Solution 2B. If cleanup fails, or if you have difficulty following these instructions, please contact Microsoft or your computer manufacturer for further assistance from a certified Microsoft technician.
