#Revision 1.3  2011/01/21 17:02:47  seanr
#PRN: 38502 - LuntBuild - LogViewer
# - fixed issue, where Setup would fail, if LogViewer was already installed.
# - now taking the buildnumber from LuntBuild (so that it is always incrementing)

#We need to perform the following changes on the Setup project:
#1. increment the final number, in the Setup version (e.g. 1.0.0 -> 1.0.1)
#2. replace the ProductCode with a new GUID
