Open Source Maintenance Fee

The WiX Toolset participates in the Open Source Maintenance Fee to support long-term, sustainable maintenance.

While the source code remains freely available under the terms of the LICENSE, organizations that generate more than $10,000 in annual revenue (as defined by the OSMF terms) are required to sponsor the wixtoolset GitHub organization to satisfy the Open Source Maintenance Fee.

Note

The Open Source Maintenance Fee was first introduced in WiX v6, but the EULA acceptance enforcement was implemented in WiX v7.

Check your Maintenance Fee payment status

If you are a FireGiant customer, log in to your account. If you see Current role: Member of <Your Company Name> then the maintenance fee is covered by your company’s WiX Developer Direct plan.

Otherwise, the verification button may be able to confirm that your GitHub account (or an organization you belong to) pays the maintenance fee for the WiX Toolset. Please note that your organizations’ access permissions may prevent this check from succeeding.

Check payment status

You will be redirected to GitHub to confirm your sponsorship status.

Accept the EULA (WiX v7 and later)

After you have confirmed that the maintenance fee is paid, accept the WiX Toolset EULA using one of the following options. The direct acceptance option is designed for use in build scripts and CI/CD. The indirect acceptance is intended for occasional manual use. See the table at the bottom of this page for the full list of EULA IDs.

Direct Acceptance

The first option to accept the EULA is to add the AcceptEula MSBuild property to your .wixproj with the appropriate EULA ID:

MyPackage.wixproj

<Project Sdk="WixToolset.Sdk/7.0.0">
  <PropertyGroup>
    <AcceptEula>wix7</AcceptEula>
  </PropertyGroup>
</Project>

Or use the -acceptEula command-line switch to wix.exe to specify the EULA ID:

C:\src\MySetup

wix build -acceptEula wix7 *.wxs -o bin\my.msi

Indirect Acceptance

Alternatively, you can accept the EULA once per-user, per-computer. This is most often used by developers who run wix.exe commands directly and do not want to specify the command-line switch each time.

C:\src\MySetup

wix eula accept wix7

MSBuild can also be used to accept the EULA.

C:\src\MySetup

msbuild -t:AcceptEula -p:EulaId=wix7

Available EULA IDs

The following table provides the EULA ID for each version of the WiX Toolset.
