Build : 'S'
OS : 95/98 only it seems NT resolves it ok.

When the installer needs to replace an older MSVCRT.dll and needs to force a reboot. On Win98/95, the system may hang or not boot at all. Then on the second boot to try to reboot after the initial boot failure. You may end up in a clean VGA boot state, which after you maybe able to recover with yet another reboot.

Getting all the resources for this bug:
  Older version of the MSVCRT.dll (distributed with Win98) is attached.
    
     Requirements:
       1. Windows 95 / Windows 98 with original MSVCRT.dll
          (original version is: 5.00.7128 distributed in 95 via Plus Pack
            and on Win98 it comes builtin)
       2. QuickView
          (you can install quickview by:
              Start->Settings->Control Panel->Add/Remove Programs
              Windows Setup tab->Accessories->Details {button}
              then goto down and enable the checkbox for QuickView then
              Apply.
                    
     In the event you cannot simply copy the older MSVCRT.dll over the existing
in Windows\System dir. Then do the following:
     
     1. Win95/98 do SHUTDOWN -> Restart in MS-DOS mode
     
     Once at a DOS prompt do the copy over:
        C:\copy {location of your copy of MSVCRT.dll} C:\{windows sysdir}
        then type EXIT
        
     
     No need to reboot. After a successful copyover.
     
     -Lock the DLL by opening it with QuickView.
       1. find the working copy of MSVCRT.dll in your {Windows' sysdir}
       2. right click on the DLL
       3. select QuickView.
       
       While the QuickView window is up. Now install Cricket/Kestrel. Because
we are replacing the old with newer MSVCRT.dll AND it's locked due to being
opened. The reboot dialog will appear at the end of your installation.
       
       When you reboot you should see:
       
       1. Win95 a blinking cursor and fails to boot.
       2. Win98 a distrubing randomly placed words stating something to the
          effect; Windows may fail to reboot....
