Assisted and checked the issue of Sir King Bueno regarding the error extraction of the report using excel on NAV.  The instance cannot be loaded of the following.NET Framework object: Assembly Microsoft office interopt. I checked if there are any needs of windows update on his PC. then tried generating the same report using the server but the table was locked and the NAV keeps on hanging due to the processor problem. I advised him that we will reinstall the NAV and the MS Office and we'll try if this will work. We'll continue this tomorrow.
