Before starting the installation you should consider the following: 
               	 
            
 
            	 
             
               		
               - Visual COBOL and 
                  		  Enterprise Developer cannot coexist on the same machine. 
                  		
               
 
               		
               - You need to be logged in with a user-ID that has write access to the registry structure under HKEY_LOCAL_MACHINE, HKEY_CLASSES_ROOT,
                  and HKEY_CURRENT_USER so the installation software can set the environment appropriately. You also need to be logged on with
                  Administrator privileges. 
                  		
               
-  Various actions and operations within your COBOL development environment depend on certain Microsoft files distributed in
                  the following packages: the Windows SDK package and the Microsoft Build Tools package. By default, a standard product installation
                  downloads and installs these. Refer to 
                  		  Microsoft Package Dependencies to see if these packages are required. If you do not plan to use your development tool in a way that will depend on any of
                  these packages, you can run a non-standard installation, which will skip their download and installation, thus saving disk
                  space and time taken for installation. Refer to 
                  		  Advanced Installation Tasks for details on the available installation options. 
                  		
               
-  If you already have Microsoft Build Tools for Visual Studio 2017 installed, you must ensure that it contains the Visual C++
                  build tools workload (or at least the individual components contained in that workload) before you run this installation.
