Are you using a standard bootstrapper? RtfLicense or HyperlinkLicense?

If you set SuppressOptionsUI="no" within the Wix standard boostrapper, this will show an options button which will allow the user to amend the install location manually.

<BootstrapperApplicationRef Id="WixStandardBootstrapperApplication.RtfLicense">
  <bal:WixStandardBootstrapperApplication
    SuppressOptionsUI="no"
    />
</BootstrapperApplicationRef>

Then as you mentioned setup a MSI property within the MSI package, this will then be overwritten with the location the user has picked.

<MsiProperty Name="INSTALLFOLDER" Value="[InstallFolder]" />

If you want to setup a default install location set a Variable within the bundle to your default value.

<Variable Name="InstallFolder" Type="string" Value="[ProgramFilesFolder]Install"/>

I can't set the default install location. I'm using the RtfLicense template and I set the Variable (inside Bundle but outside Chain) but the initial install folder is empty. — bubi, Sep 17 '17 at 16:21
