New Install MDK529 but problem with debugger

I am trying to use the Tiva C Series TM4C123G evaluation kit, installed Keil for the first time, loaded an example but when I try debug I get the following :

Error:
Cannot load driver 'C:\Keil_v5\ARM\BIN\lmidk-agdi.dll'.

Possible Reasons:
- Driver DLL could not be found in the specified path
- Driver DLL requires additional DLL's which are not installed
- Required Hardware Drivers are not installed
Debugger aborted !

Indeed, the C:\Keil_v5\ARM\BIN directories exist with plenty of files (72) but no lmidk-agdi.dll. Searching around, I am unable to find anything of use. 

Any pointers would be much appreciated !
