Registry issues? Please help!

Be my hero and help us solve this.  We have been struggling to get this working for a couple of days. 
 

 We tried to install as the administrator as follows:
 
 C:\Windows\system32>blat -install oursite-com.mail.protection.outlook.com [email protected] 3 25 ProfileName
 

 Here is the error we get in the log file:
 

 
 2017.03.22 14:09:53 (Wed)------------Start of Session-----------------
Blat v3.2.16 (build : Aug  7 2016 22:51:52)

Failed to open registry key for Blat
To set the SMTP server's name/address and your username/email address for that

or use '-server <server_name>' and '-f <your_email_address>'
aborting, nothing sent

 Here are the permissions for the registry key:
 
 Everyone - Read
CREATOR OWNER - Special
SYSTEM - Full Control 
Administrators - Full Control
Users - Read
 

 Here the information from the event viewer:
