!include LogicLib.nsh

#support.microsoft.com/kb/188768
!define WFT_SEC 10000000
!define WFT_DAY 864000000000

var /GLOBAL installTime
var /GLOBAL expiredTime
var /GLOBAL currentTime

System::Call kernel32::GetSystemTimeAsFileTime(*l.s)
System::Call kernel32::FileTimeToLocalFileTime(*ls,*l.s)
Pop $currentTime

ReadRegStr $installTime HKCU "Software\MyCompany\MyApp" "InstallTime"
${If} $installTime = 0
    StrCpy $installTime $currentTime
    WriteRegStr HKCU "Software\MyCompany\MyApp" "InstallTime" $installTime
${EndIf}

System::Int64Op ${WFT_DAY} * 30 ; You could calculate this with calc.exe if it is always 30 days
Pop $0
System::Int64Op $installTime + $0
Pop $expiredTime


DetailPrint $$currentTime=$currentTime
DetailPrint $$installTime=$installTime
DetailPrint $$expiredTime=$expiredTime
System::Int64Op $currentTime > $expiredTime
Pop $0
DetailPrint "30 days after $$installTime: $0"
