Solution
Using a special syntax the Custom Command tool does allow execution of Windows Command Line commands.
You must include cmd.exe /c before all Windows Command Line commands you wish to execute.
For instance, to create a directory called
Test at the path
C:/Users/admin/Desktop from the Windows Command Line you would execute the line:
mkdir "C:/Users/admin/Desktop/Test"
To execute this same command from the Custom Command utility in the TestStand Deployment Utility Installer Options simply add cmd.exe /c to the beginning of the command as shown below:
cmd.exe /c mkdir "C:/Users/admin/Desktop/Test"
You must do this for each Windows Command Line command you wish to execute.
