NSIS Error. Installer integrity check has failed.

How do I fix the problem?

There are a number of ways the installer can be modified, but we'll cover steps to fix the problem on your end. If all these steps don't work, please contact the developers or publishers of the software you are attempting to install or your normal computer support channels.


If the software was obtained from the Internet

  1. Clear your browser's cache.
  2. Disable any download accelerators or managers and download the installer again.
  3. Rename the installer so it is a simple one-word name with no special characters (without removing the .exe suffix)
    • Example: install.exe
  4. Download the installer from another source approved by the software developer or publisher.
    • It might be corrupted on the server, or the connection to the server is unreliable from your location.
  5. Update your anti-virus software (if installed) and download the installer again.
  6. Disable your anti-virus software and download the installer again.
  7. Download the installer using another computer and copy it to the original computer.
  8. If you have the nVidia firewall installed, uninstall the program and download the installer again.
  9. Scan for, and remove malware and viruses on your system.
  10. Scan the hard drive using scandisk, chkdsk, or any other hard drive repair tool.
