Thanks you. Very useful.
With this information I could see that the font_mask is empty when it calls the string {\style} and why the installation is wrong. To get the font mask is reading a MSI record called #ICM but I could not find any information in the web. The problem is this function with the record and package #ICM in the field 10:
LPWSTR msi_get_deformatted_field( MSIPACKAGE *package, MSIRECORD *rec, int field )
Values are: #ICM, #ICM,10 font_mask = msi_get_deformatted_field( dialog->package, rec, 10 );
Someone could give me more information of package or record ICM?
Cheers.
