////////////////////////////// REQUEST #1 /////////////////////////////////////////
I'm workin' on Nero 8.3.20.0 Lite/Micro true addon (english/french). One thing missing : i plan to check reg entries about nero previous versions(v7/v8).
If ONE of these reg entries is found, a message will prompt user : "A previous version of Nero has been founded on your system. Please uninstall it before continuing.". This will abort addon installation.
I'm tryin' to use CustomDestination directive to check Windows registry. But i'm little bit confused about its using.
[Install.Nero8Lite]
11,,rundll32.exe,,,"advpack.dll,LaunchINFSection %01%\Nero8L.inf,Install"
[Install]
BeginPrompt = ...
CustomDestination = Nero.PreviousVersions.Detected
RunPreSetupCommands = Create.i386:1,MSVC++2005.Check:1,Nero8PreInstall.Check:1
[Nero.PreviousVersions.Detected]
49000=Nero7Lite.Check,22
[Nero7Lite.Check]
"HKLM","SOFTWARE\Nero\Installation\Families\Nero 7","","%Nero7Lite_FOUNDED%.",""
[Strings]
Nero7Lite_FOUNDED="A previous version of Nero has been founded on your system. Please uninstall it before continuing"
Durant my tests, this above prompt message is shown, even there's no regentries for NERO.
