Problem of using Pdfcreator in foxpro 7

I would like to print pdf in Foxpro 7 in command

And I use the following code

oPDFC  = CREATEOBJECT(“PDFCreator”,“pdfcreator”)
oPDFC.cStart("/NoProcessingAtStartup")
oPDFC.cOption(“UseAutosave”) = 1
oPDFC.cOption(“UseAutosaveDirectory”) = 1
oPDFC.cOption(“AutosaveFormat”) = 0              &&  ; 0 = PDF format
DefaultPrinter = oPDFC.cDefaultprinter
oPDFC.cDefaultprinter = "pdfcreator"
oPDFC.cClearCache
ReadyState = 0
oPDFC.cOption(“AutosaveFilename”) = "mypdf"
oPDFC.cOption(“AutosaveDirectory”) = ".\personnal"
oPDFC.cprinterstop=.F.
REPORT FORM myreport TO PRINTER
SET PRINTER TO  NAME (lcoldPrinter) && Fix this 
oPDFC.cDefaultprinter = DefaultPrinter
oPDFC.cClearCache
RELEASE oPDFC

But the following error appear
"Class deifnition pdfcreator.clspdfcreator is not found"

How can I solve?

Thanks you so much
