Problem:

When trying to use XML it produces the following error:

Load error : file 'MFCHK_XMLGENERATE'

error code: 173, pc=1F9, call=1, seg=0

173     Called program file not found in drive/directory

Resolution:

The problem is that the product used is not the supporting xml generate.

You can easily check this out if the following xml modules exist or not:

XMLCHK

XMLCHKE

XMLCHKP

XMLCHKEP

If not then an upgrade is necessary. It is supported as of Server Express 4.0 SP3.
