Open CMD as administrator. locate the exceptions folder. "cd C:\CS6_MC_Windows_x32\Exceptions". Now, run this command: ExceptionDeployer.exe --workflow=install --mode=pre
2. Deploy the main MSI.
Open CMD as administrator. locate the Build folder. "cd C:\CS6_MC_Windows_x32\Build". Now run this command: Msiexec.exe /I <path of MSI> /qn for silent install or just msiexec.exe /I <path of MSI>
3. Run the exception deployer application again in post mode. This wil install remaining exceptions.
Open CMD as administrator. locate the exceptions folder. "cd C:\CS6_MC_Windows_x32\Exceptions". Now, run this command: ExceptionDeployer.exe --workflow=install --mode=post
