Most people only use a tiny fraction of the power of Microsoft Office when typing documents or spreadsheets.  When you run EstimatorXpress we are using a large portion of the power of Excel and tapping into functions that are rarely used by most people.


What we have experienced since the launch of Office 2010 (and with Office 2013 and 2016) is that Microsoft Office does not seem to install all its components very successfully.  This tends to manifest itself to the user as EstimatorXpress often freezing or giving messages about Excel and has stopped working, and it also causes some EstimatorXpress crash messages as well.


This all sounds a bit grim, but the fix is very simple indeed.


On your computer, go to Control Panel, and then your list of installed programs (the place where you would click on a program to uninstall it)


Now find Microsoft Office in your list - click on it once and you will then see the "Change" option appear on the menu above


Click on Change and this will give you various options depending on which version of Microsoft Office you have - you want to select the Repair option.   On Office 2013 and 2016, you normally are given 2 repair options - Quick Repair and Online Repair. The Quick Repair does fix the problem most of the time and takes about 5 to 10 minutes.  If this does not solve the problem, you can try the Online Repair - this can take several hours depending on the speed of your internet
