CRM Outlook Client Error "input string was not in a correct format"

 

I ran into an issue with the CRM Outlook client configuration wizard that turned out to be a quick registry edit:

 

Set sPositiveSign to “+” at

 

HKEY_CURRENT_USER.Control Panel.International

 

Make sure to update the Default and all profiles under HKEY_USERS if the person running RegEdit is not the actual user (e.g. a desktop support person)
