MSIEXEC Unregistered
Hello,
My application launches product's MSI using InstallProduct. This application needs to perform some validations before installing MSI. MSI Service state is one of those validations I need to know about. If the user does something like this from command prompt --- "msiexec /unreg", application fails to install. How can I validate whether the service is unregistered or not.

If your users have rights to register and unregister COM containers, then you deserve everything you get!
Anyway, even a passing knowledge of how registrations work would surely lead you to check the WindowsInstaller.Installer entry in the registry, HKEY_CLASSES_ROOT\WindowsInstaller.Installer\CLSID.

D'oh! [red-faced]The header I put at the top of ALL my WI scripts is now proved wrong. I've had it for so long, I took its content as read, but I had things the wrong way round.
WindowsInstaller.Installer "belongs to" MSI.DLL
MSI.Package "belongs to" MSIExec.EXE.
Sorry about that.
