Hi,
After Windows update KB4041681 OLEDB connection stop working.
THIS CODE stop working:
using (OleDbConnection conObj = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\a.XLS;Extended Properties=Excel 8.0;"))
{
conObj.Open();
RISE ERROR:
EN: Unexpected error from external database driver (1). (Microsoft JET Database Engine)PL: Nieoczekiwany błąd (1) w sterowniku zewnętrznej bazy danych.
After unistall update KB4041681 all is OK.
ANY other workaround then removing update KB4041681?
