Gents, have you checked your InstallAgent.vbs script in the latest version ?

Windows 8.0

As I can see, that doesn't work at all in InstallAgent.vbs:

 if(Cdbl(currVer)>Cdbl(latVer) or (Cdbl(currVer)=Cdbl(latVer) and Cdbl(currSP)>=Cdbl(latSP) )) then
  'Wscript.Echo "already in latest version, so no need to download the agent again."
  Wscript.quit(0)
 end if

MSI will be never installed for any params.

It should be something else:

if(not isNull(latestAgentVersion) and latestAgentVersion <> "")then

 latMaVer = Left(latestAgentVersion,Instr(latestAgentVersion,".")-1)
 latMiVer = Mid(latestAgentVersion, Instr(latestAgentVersion,".")+1, InstrRev(latestAgentVersion,".")-Instr(latestAgentVersion,".")-1)
 latSP = Mid(latestAgentVersion,InstrRev(latestAgentVersion,".")+1)

 currMaVer = Left(currentVersion,Instr(currentVersion,".")-1)
 currMiVer = Mid(currentVersion,Instr(currentVersion,".")+1, InstrRev(currentVersion,".")-Instr(currentVersion,".")-1)
 currSP = Mid(currentVersion,InstrRev(currentVersion,".")+1)

'Wscript.Echo "Latest: " & latMaVer & ", " & latMiVer & ", "  & latSP
'Wscript.Echo "Current: " & currMaVer & ", " & currMiVer  & ", " & currSP

 if( (Cdbl(currMaVer)>Cdbl(latMaVer)) or _
            (Cdbl(currMaVer)=Cdbl(latMaVer) and (Cdbl(currMiVer)>Cdbl(latMiVer))) or _
            (Cdbl(currMaVer)=Cdbl(latMaVer) and Cdbl(currMiVer)=Cdbl(latMiVer) and Cdbl(currSP)>=Cdbl(latSP) ) ) then
    Wscript.Echo "already in latest version, so no need to download the agent again."
    Wscript.quit(0)
 end if
end if
Wscript.Echo "Going to install."

Please check and fix. Thanks
