I have a SQL 2014 dev instance running on a windows 2012 R2 OS
I have upgraded a 2012 version to 2014, and one of the developers has noticed the debug button in MMS isn't working.
When clicking you get the following error:
Failed to start debugger
------------------------------
ADDITIONAL INFORMATION:
Data is Null. This method or property cannot be called on Null values. (System.Data)
Click okay then you get :
Unable to start a program 'MSSQL;;//INSTANCE/DBNAME/sys/=0
I have looked all over google with no solution. The SQL service account is running under a domain account which is in the sysadmin role, so not a permissions thing there. Also management studio is running local to the instance so its not a remote connection issue. There is nothing in event viewer or SQL logs to indicate a problem.
I would appreciate any help or advise on this please.

Dear, have it been resolved? I am facing the same issue, not able to debug when run in Admin and connect to local DB.
