Installation Instructions:
============================

Simple installation:
	Before installing, stop the LifeKeeper service and exit from any LK GUI
	processes running on the node being updated.

	Run - as Administrator -  the "Install.cmd" script included in this patch.
	
	After installation, restart LifeKeeper.

Manual installation:
	Before installing, stop the LifeKeeper service and exit from any LK GUI
	processes running on the node being updated.
	
	On each node, run the following commands in an Administrator command prompt.
	Note that <patch_folder> is the full path to the folder containing the
	updated cygwin0.dll file.

	cd /d %LKBIN%
	move /y cygwin1.dll cygwin1.dll-Save
	copy <patch_folder>\cygwin0.dll cygwin1.dll

To verify installation:
	Start a CMD prompt.  In the prompt run these commands:

	cd %LKBIN%
	sh 
	export PATH=/bin:$PATH
	rm -f NUL
	rm -f NUL:
	echo > NUL
	echo > NUL:
	ls NUL* 2> /dev/null | wc -l

The last command should output "0"

Uninstallation Instructions:
============================

Simple uninstallation:
	Run the SIOS LifeKeeper installer, and choose the 'Repair' option.
	Reboot the system.

	Restart the LifeKeeper service.
