Excel start ups and crashes

[ErikaKovacs]

I am attempting to use the trial version of ESRI for Office.  Excel crashes and restarts several times before finally crashing completely.  I can view the ESRI Maps tab under File, but I cannot do anything.  Excel locks up and then crashes. 

When I uninstalled ESRI Maps for Office, Excel worked normally again.  When I reinstalled it, the crash cycle began again. 

Any suggestions on how to stop this from happening?  I verified that I downloaded the correct bit version. 

Thanks
Erika

Are you using the Portal web adaptor?  Are you certain that the URL you are inputting during installation and/or configuration of the tool is valid?  Try that exact link from the PC you are running Excel from to make sure that it resolves correctly.  I seem to remember that the URL for EMO should not be the home page URL for Portal or AGO.  For example, with Portal the typical home page URL via the web adaptor would be something like http://gisserver.domain.int/arcgis/home where 'arcgis' is the default name of the web adaptor but the URL you would configure for EMO during installation would be something like http://gisserver.domain.int/arcgis without the 'home' part of the URL.
