Wix setup Error 0x8007007a: Failed to copy SqlScript.Script or Error 0x8007007a: failed to read SqlScripts table

You are trying to install an application and in the detailed log you get something like this:

InstallSqlData:  Error 0x8007007a: Failed to copy SqlScript.Script: SqlWithWindowsAuthUpv2.9.5UpdateGetInstallJobBuildByInstallJobBuildIdScript

or

InstallSqlData:  Error 0x8007007a: failed to read SqlScripts table

For me it was related to the length of an <sql:SqlScript> tag Id property. If you are trying to use more than 55 characters for the BinaryKey property, you get a build error that you should use a max of 55 characters. For the Id you get no such warning, but instead it fails on install.

I hope it helps people (I lost two hours figuring it out).
