# Obtain SMC installation files

Before running the installer, you must download the correct installation file from the download page and make sure that the checksums are correct.

##

You can check the installation file integrity using the file checksums. The checksums are on the installation DVD and in the release notes. In Windows environments, you can use Windows PowerShell to generate checksums. Several third-party programs are also available.

We provide only recent versions of the software for download. We recommend that you store the upgrade files yourself to make sure you can install the exact same version later (for example, if there is a hardware failure). This is recommended especially if your organization’s policies mandate lengthy testing periods that limit the speed of adopting new versions.

## Steps

1. Download the installation file from https://support.forcepoint.com/s/download.
   Separate .zip packages are available for downloading installation files for all supported platforms or just one supported platform.
2. Browse to the directory that contains the files to be checked.
3. Generate a checksum of the file.
   Examples in a Linux environment where `filename` is the installation file:

       sha1sum filename
       sha256sum filename
       sha512sum filename

   Example result:

       sha1sum smc_1.0.1.1000.zip
       79785edab5d2a1191a3065510756f72883952455 smc_1.0.1.1000.zip

4. Compare the displayed output to the checksum on the website.
   CAUTION:
   Do not use files that have invalid checksums. If downloading the files again does not help, contact Forcepoint Customer Hub to resolve the issue.
5. Unzip all folders and files in the archive to the server you want to upgrade.
