Power Query Add-in should be enabled automatically after excel crash

When there are two or three power view sheets in the same excel workbook, most of the times excel is crashing and disabling the Add-in. There should be some ways to avoid the below problems: 1.Excel should not crash when the data is within the size limit mentioned by PowerBI Team. If excel crashes user may lose the data if he/she didn't save data frequently. 2. All users might not be aware how to enable the power query Add-in. Hence Add-in should be enabled automatically even if the excel crashes
