Thanks for the code, Robert!

But I too encountered the deletion problem. A colleague of mine searched and found the (somewhat unintuitive…) solution. Before returning from GetMsiProperty, do:

if (record != null)
{
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(record);
}
view.Close();
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(view);
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(database);

Hello
I’ve read your post on Alteridem Consulting Website about reading properties from an MSI file.
I use GetMsiProperty function to find out MSI file version, but I encouraged a problem while trying to delete file after I’ve checked it’s version.
It seems like the file is still in use by GetMsiProperty function. I tried to find some closing function but I didn’t succeed.

Maybe you know something I forgot to do while reading Msi version?

I would appriciate any help.
