An MSP is simply a transform which turns one MSI into another MSI. If you can do it in an MSI, you can do it in an MSP. Simply write your Custom Action into your new MSI & Condition it with the PATCH property so it only runs during patching. It should then be run when your MSP is applied to the target system.
You can't access files inside your cabs until they are installed on the machine. If you need some functionality of that manner you would need to use a Binary Element to embed the file itself in your MSI outside of the cab which can then be used in Custom Actions. Personally for checks such as the ones your describing, I would use Launch Conditions to stop the install before it even gets started if the pre-requisites don't exist on the target machine (to save users & your QA wasting time waiting for an install to run through which is going to fail & rollback once it gets to the checks). If you're bootstrapping those pre-requisites this can be used a "belt and braces" approach to ensure the install can't continue even if the pre-req installer failed during your bootstrapper sequence.

I'll elaborate a bit more about what we need. Basically what our client needs is when installing a patch, to check if certain middleware assembly versions is installed (which our client will install). When we make the application build it is not certain what those middleware assemblies versions will be, so I was thinking we could pass the version numbers with the patch to the custom action to check whether they are installed or not, by using properties or some other means, but I'm getting the feeling that msp's don't support properties. Something I just thought about, can a custom action access a file in the contents cab file of the patch? If it's possible then I can include an xml file and access that to get the version numbers. Or another thought I just had is to even install the xml file to a dir and then to run the custom action after InstallFiles, and the report an error if the assemblies were not found. What are your thoughts on this?

Subject: Re: [WiX-users] Patching and properties Patches don't have versions. The version would be the ProductVersion of the new version your patch is upgrading the old version to. I don't quite understand your question regarding passing properties to Custom Actions. Can you elaborate on what you're trying to do?

And also I want to know if it is possible to get the patch version being installed with a custom action. I did run the following command : "misiexec /update patch.msp /l*v logfile.txt", but I didn't see the a patch version property somewhere, only the patch description etc Regards, Henk Roos "DISCLAIMER: This message is proprietary to Aricent and is intended solely for the use of the individual to whom it is addressed.
