This is happening with a single table MS Query in Excel 64-Bit when accessing large individual I/M and P/R files and continues after rebuilding them (Ex. IM_ItemTransactionHistory) . I reviewed the other thread on this error, but nothing applies other than the exact message and Sage 100 level 2019 (version 5 in this case). It does not happen in 32-Bit Excel and I have properly installed and re-installed the 32/64 Bit ODBC driver. I also get a similar error when using 64-Bit Power query. I'm thinking this has to be something installation dependent, but they have no 3rd party add-ons and is a straight distribution setup.
