Can not uninstall Exchange 2007 64 bit. -

Question

I am in a bit of a pickle here and hope that someone has some suggestions.
 Recently, 6 months ago we upgraded to server 2012 and Exchange 2013 64 bit.  
Everything has been moved from the 2003 server / 2007 exchange environment and seems to be running correctly.   
To be honest the 2003 server was cut off for a few weeks just to make sure that everything was completely moved over to the 2012/2013 environment.  
Good news here is it all works except for Exchange 2013 fussing about not being able to see the 2007 exchange server.  
Goal:   Completely remove Exchange from
this server followed by removing the server from AD.   It is 7 years old and I want to
cut it off forever.
Problem:   Exchange will not uninstall.   Per
paid support call to Microsoft I was told if I wanted to completely and properly remove all instances of this server from my Exchange environment and AD environment I must use the add/remove programs method to do so.   Unfortunately this process
fails as well as several other items on this server.
Environment / Work done so 
far:    The 2003 server running 2007 Exchange was also an AD server.  
Yes I know it’s a non-supported environment, but it’s what I was handed and it seemed to work for years.  
I have checked and this server is not running any FSMO roles anymore.   
When I try to remove the application Exchange, through add/remove programs, I get a little gray box that comes up and says… “Microsoft Exchange Server 2007 Setup Initializing”.  
After about 3 or 4 seconds the box disappears and nothing further happens.  
The same thing happens when I try to “Change” the application.
Other things of interest:
The Exchange Management Console will not load either.The error message is:CLSID:FX:(76dd58f7-54ba-42e3-a2e0-dbfb674539f)    
The Exchange Management Shell will not seem to execute any commands either.I get several messages, but most have the following:“The type initializer for ‘InstanceContext’
threw an exception.
I downloaded service pack 3 and tried to install, but that failed as well.
The follwoing Exchange related services will not run.
Microsoft Exchange EdgeSync
Microsoft Exchange IMAP$
Microsoft Exchange Mail Submission
Microsoft Exchange POP3
Microsoft Exchange Replication Service
Microsoft Exchange Search Indexer
Microsoft Exchange Service Host
Microsoft Exchange Transport
Any suggestions / help would be greatly appreciated.

Ok, the command did not work, but it did lead to the answer I think.  However, I'm not sure how to get this working.   Please remember that the console will not load and the all commands, but the help command fail inside the shell.  
The exact error message is:
Part 1
----from log file after failed setup /m:RecoverServer
The user who's currently logged on doesn't have sufficient permissions to install this package. You need at least Exchange Server Administrator permissions on the current computer to complete this task.

If I use the command:   Add -ExchangeAdministrator -role OrgAdmin -Identity contoso\Ted
I get:
