2010-01-05 09:06 AEST by Arthur Barrett - Armin Müller reports to the TortoiseCVS team that during uninstall "I can't answer the question (Yes-
No). No clue what it is asking me."

The src\RunTimeInstaller\RunTimeInstaller.c installs the cvsnt client using msiexec and a series of 
option depending on the parameters passed from the tortoisecvs ISS scripts:

    DBG("Installing CVSNT\n");   
    lstrcpyA(buf, "msiexec ");   
         
    if (!WindowsVersionIs2K())   
        lstrcatA(buf, "/norestart ");    // Win2K does not support this      

    // If custom, show default UI
    if (lstrcmpA(argv[2], "custom"))
    {
        if (silent)
            lstrcatA(buf, "/qn ");      // No UI
        else
            lstrcatA(buf, "/qb ");      // Basic UI
    }
    DBG("Installing CVSNT\n");   
    lstrcpyA(buf, "msiexec ");   
         
    if (!WindowsVersionIs2K())   
        lstrcatA(buf, "/norestart ");    // Win2K does not support this      

    // If custom, show default UI
    if (lstrcmpA(argv[2], "custom"))
    {
        if (silent)
            lstrcatA(buf, "/qn ");      // No UI
        else
            lstrcatA(buf, "/qb ");      // Basic UI
    }
        lstrcatA(buf, "/i ");    
    lstrcatA(buf, argv[1]);      
    lstrcatA(buf, "\\" CVSNTINSTALLER);      
    if (!LaunchCommand(buf))     
        return 3;



This msiexec display options are:
	/q[n|b|r|f]
		Sets user interface level
		n - No UI
		b - Basic UI
		r - Reduced UI
		f - Full UI (default)


If the installer is called with no UI then prompts will not be visible to the user.
