Satanic Verses sayeth:  "The Codepage Summary property must be set
before any string properties are set in the summary information.", but
so far as I can tell, PID_CODEPAGE is never used in msilib.__init__.py,
etal.

Confirming evidence: msilib's GetProperty(msilib.PID_CODEPAGE) raises
"Not Implemented" on Python2.5.1's own .msi file.

It's been more than a year.  I'll work a little longer on the
SetProperty(...) example, but here's the "confirming evidence".

A related problem is 1884, but I simply don't remember the context and
long ago deleted the code in disgust.

I think you are misinterpreting the documentation. It doesn't say that the codepage property is required (in fact, they explicitly list the required properties, namely Template, Revision Number, Page Count, Word Count). What they do say is that *if* you want to set the codepage property, *then* you must set it before any other string property. Since we are not setting the codepage property at all, this requirement is irrelevant.

Closing the report as invalid.
