How to detect a running MSI Installation

Question

I'm looking for a way to detect if a Windows Installer installation is already in progress. What I've found out so far is:

Checking the Registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\InProgress
Using the Windows Installer API function MSIInstallProduct with a dummy file which then would return the specific error code.

Does anybody know a smarter solution?
