0patch Agent fails to install – Help Center

If 0patch Agent installation fails, please try some of the following as applicable:

If on Windows 7 or Server 2008 R2, make sure you have January 2020 Windows Update installed.
Download the installation package again and try installing the agent again.
Restart your computer and try installing the agent again.
If you have any other security software installed on the computer, check its alerts, logs and quarantine for any events or files related to 0patch.
Check for known compatibility issues with other software products.
If 0patch Agent has been installed on the computer before, manually clean up any of its residues:
1. Execute sc delete 0patchService to delete the 0patch service.
2. Execute sc delete 0patchDriver to delete the 0patch kernel driver.
3. Delete the entire 0patch folder under c:\Program Files (on 32-bit Windows) or c:\Program Files (x86) folder (on 64-bit Windows), or wherever you tried to install 0patch Agent if you chose not to use the default location.
4. Launch regedit.exe as administrator and delete the entire HKLM\Software\0patch registry key.
5. Try installing the agent again.
If you can't fully uninstall 0patch Agent, try using Microsoft's Program Install and Uninstall troubleshooter. (Note: Microsoft Edge won't let you download this Microsoft's tool with a valid signature by simply clicking on the link, claiming it could harm your computer. You can still download it by right-clicking on the "Download troubleshooter" link and selecting "Save link as")
