Hello Poojitha,
Welcome to Microsoft Community. I understand that you're facing an issue installing the On-Premises Data Gateway for Power BI, with the error log suggesting insufficient disk space and other issues, even though you seem to have sufficient resources. Let’s work through this step by step to address the problem. Troubleshooting Steps
- Ensure Sufficient Disk Space Even though you mentioned having adequate space, the error points to a disk space issue. Check available space on your system drive (usually C:). Ensure at least 5–10 GB is free, as temporary files may require additional space during installation. You can clean up disk space by using the
Disk Cleanuputility (Windows + S> search "Disk Cleanup"). - Run the Installer as Administrator Right-click the installer file and select "Run as administrator." This ensures that the installation process has the necessary permissions to proceed.
- Check Windows Installer Service Open
Servicesby typingservices.mscin the Run dialog (Windows + R). Look for the "Windows Installer" service, ensure it’s running, and set it to "Automatic" if it’s not already. - Temporarily Disable Antivirus and Firewall Security software may block certain actions during the installation. Temporarily disable your antivirus and firewall, then try reinstalling. Remember to re-enable them afterward.
- Clear Windows Installer Cache Sometimes, cached installation data can cause issues. Open the Command Prompt as administrator and run the following commands:
net stop msiserver del /f /s /q %windir%\installer*.* net start msiserver Restart your PC and try installing again.
- Use the Microsoft Installation Troubleshooter Download and run the official Microsoft Program Install and Uninstall troubleshooter to identify and fix issues with the installation.

- Check for Windows Updates Ensure your system is up to date. Go to
Settings > Update & Security > Windows Updateand install any pending updates. An outdated system can lead to compatibility issues during installation. - Re-download the Gateway Installer The file may have become corrupted during download. Download the latest version of the On-Premises Data Gateway (personal mode) from the official Power BI website and try again (Link: https://powerbi.microsoft.com/en-us/gateway/).
Note Regarding Troubleshooting Steps You can try running the installer as an administrator and ensuring sufficient disk space first, as these steps often resolve similar installation issues. If the problem persists, clearing the Windows Installer cache or using the troubleshooter may help.
