HI,  I try the PB 2019 R3 Build 2556 Runtime 19.2.0.2556

before install this version this code work

oleobject loo_excel
loo_excel = create oleobject
ll_rc=loo_excel.connecttonewobject("excel.application")
loo_excel.visible=false
//
loo_excel.workbooks.open(st_3.text)
//
loo_excel.activecell.currentregion.select()
loo_excel.selection.copy()
dw_1.importclipboard(2)
clipboard("")
loo_excel.Application.Activeworkbook.close(false)
