Thanks for the detailed info! I think all that’s missing is to untar each of the .tar files in the C:\Geant4\geant4_10_06-install\share\Geant4-10.6.2\data directory. If Windows can’t do this directly, cmake can do so by running (from the cmd prompt in the that directory), I think:
> cmake -E tar xf G4ABLA.3.1.tar.gz
and so on for the remainder. If your environment variables for the data are pointing the to directory names, e.g. G4ABLADATA is set to C:\Geant4\geant4_10_06-install\share\Geant4-10.6.2\data\G4ABLA3.1, then things should then work. If the variable values include the .tar or .tar.gz extension, simply remove them from the value.
