I'm creating a graph, but in some stations I get the following Error: "OLE error code 0x800401f3: Invalid sequece class."

The code for test is below:

#DEFINE CRLF CHR(13)+CHR(10)
#DEFINE TAB  CHR(9)
#DEFINE coltype -4100        &&Column graph
#DEFINE CAP_LOC "TITULO"     &&Títle of graph

SET SAFETY OFF
CREATE table tgraph (gen1 g) && Creates temp table
APPEND blank                 && Add blank record
lcData = " " + TAB + CAP_LOC + CRLF &&Data of the blank graph
APPEND general gen1 class "msgraph.chart" DATA lcData 

It happens in just one station with Win98 VFP 6 + SP5 + Staroffice + IE 5.0 installed. In other stations this code works fine, but I'm afraid the same error could happen in a client Station.

Could someone help me to discover what this error means and/or why it happens in a station and not in others.

Thanks in Advance.
