Conditionally install a component?

[johnw73]

I have several components that I wish to have installed ONLY if a given property is passed to the MSI at install time. This property is defined in the property manager and no value is populated for it.

For each component, I have set the condition to CUSTPROP="YES".

I then run msiexec /i foo.msi CUSTPROP=YES. However, the files are installed, despite me passing the property.

Is there any way to do this, other than just duplicating the ISM and stripping those files out?

If the component conditions are CUSTPROP="YES" and CUSTPROP=YES is passed on the command line, the components using this condition should get installed. Do the components get installed even if you don't set CUSTPROP=YES on the command line?

Yes - the files are installed even if the parameter is not specified. It's almost like it's not there at all.

A verbose installation log (with /l*v switch) may provide some crucial clues to this behavior.

Attached. I had to obscure a few things for confidentiality reasons. I have done search & replaces so the substitutions should be consistent.

One of the components i'm trying to not have installed is NFOENU4.DLL.
The parameter I'm passing is YYYSETUPTYPE=ZZZ

Note that there is a similarly named property, YYYINSTALLTYPE, which should not play a role in this.

Unfortunately I don't see anything that is of any help in resolving this problem. You may want to post a screenshot of the component with the condition.

If you have a support contract with Macrovision, you may want to contact them directly.

Thanks very much for taking the time to look at this. Attached is a screenshot.

If worse comes to worse, I guess I'll just create a new project and do dual maintenance. 😞

While I don't see any reason why this would work, try simplifying the condition. Instead of only allowing the component to install if a property is not equal to "ZZZ", try allowing the component to install only if the property is not defined:
Not YYYSETUPTYPE

Then, on the command line, pass YYYSETUPTYPE=SomeValue.

Does that change the behavior?

Component properties look fine to me. Perhaps you want to try it on a different machine or a clean machine, if you have not already done so. Other than that, I am out of ideas at this time.
