In solenv/bin/modules/installer.pm find the line: # if there are Merge Modules, they have to be integrated now The problem is that it is a terrible idea to integrate MS VC++ runtime merge modules into all language msi files (109 in case of a release build), then drop those msi files later, when the transforms are made. Instead, let's generate language transforms first, and integrate merge modules later, into the final multi language msi file. It could save 2-3 hours on an average build machine, when all languages are built.
