Phil,
Thanks for reply. Do you refer to this
1. Call the MsiQueryProductState
<http://msdn2.microsoft.com/en-gb/library/aa370363.aspx> API
2. Pass in the product code for the package that you want to detect
based on the list below
3. Check the return value of this API. If it is anything other than
INSTALLSTATE_DEFAULT, the package is not yet installed
How do I call this API? Aaron describes this as the procedure in the
VS2005 redistributable bootstrapper.
- How do I add this to the wixproj file that defines the bootstrapper
built with Votive and MSBuild?
- How can I ensure in my .MSI that the bootstrapper has been started to
install the redistributable if necessary?
But this article and the link to the corresponding VS2005 article
http://blogs.msdn.com/b/astebner/archive/2007/01/16/mailbag-how-to-detect-the-presence-of-the-vc-8-0-runtime-redistributable-package.aspx
show some GUIDs that I found after installing the redistributable
version. This could be used to find it in the registry. But I would use
a better approach if possible.
Regards,
Helge
