I'm building an installer package for an application, and would like to merge the MSM for the VC runtime into it.
Using Orca, this works fine and without conflicts.
Using msimerg, I get an error code 1629 (ERROR_DATATYPE_MISMATCH), but no further information, and no _MergeErrors table is generated.
Is there a way I could find out where the error occurs specifically?
That error just means that there is a schema difference between the two databases. The version of msimerg you're using might have a hard-coded schema requirement that could be old if it's an older version of msimerge.exe.
