Windows 7 Cannot install IIS (or any other feature I try)

[Jubs]

Hi All,

When I go into Turn Windows Features on or off and select the various IIS components I require it goes away and the progress bar gets to 99% before I get a message saying. "An error has occurred. Not all of the features were successfully changed." If I look in the CBS.LOG file I can see it installs just about everything OK before getting to a point were the attached log takes place. As you can see, the error seems to come from an interface in sppinst.dll but I'm really not sure what is going on. A bit more info. I get errors when I switch on any features, not just IIS but it is always around spp installer. I need IIS to work and this is really frustrating me! Help! Oh yes, I've tried this as Administrator etc but with no joy.

Many thanks
Julian

Julian, Experiencing issues with installing Windows features like IIS can indeed be frustrating, especially when it consistently encounters errors related to the Software Protection Platform (SPP) installer. This problem seems to be tied to the sppinst.dll file, which is part of Windows' Software Protection service responsible for managing product activation and validation. Here are some steps you can take to troubleshoot and potentially resolve this issue:

1. Check System Files:​

• Run the System File Checker tool to scan and repair corrupted system files. Open Command Prompt as an administrator and enter:

   sfc /scannow

  2. Check Component Store:​

• Try running the Deployment Image Servicing and Management tool to fix Windows corruption errors:

   DISM /Online /Cleanup-Image /RestoreHealth

  3. Check Windows Update:​

• Make sure your system is up to date with the latest Windows updates. Sometimes, missing updates can lead to feature installation issues.

  4. Check Application and System Event Logs:​

• Review both the Application and System Event Logs in Event Viewer for any relevant error messages that might provide further insight into the issue.

  5. Reset Windows Update Components:​

• Resetting the Windows Update components could also potentially resolve the issue. You can do this by running a batch script that resets these components.

  6. Install IIS Using PowerShell:​

• If the GUI method continues to fail, you can try installing IIS using PowerShell commands. This can bypass any potential issues with the GUI installer. Here's an example:

   Install-WindowsFeature –name Web-Server -IncludeManagementTools

  Additional Notes:​

  • Ensure there are no third-party antivirus or security software interfering with the installation process.
  • Reboot your system after trying each troubleshooting step to ensure changes take effect.
  By following these steps, you may be able to resolve the issue preventing you from installing IIS and other Windows features successfully. If the problem persists, further investigation into the specific error messages in the logs might be necessary to pinpoint the root cause. Feel free to try these steps and let me know if you need more assistance!
