@Prashant, no. Those properties only list patches being installed or removed. Why do you need to detect which MSPs are installed within your product session? Having to know this usually means that you're trying to condition things which you should try to avoid.

Also, once an MSP is selected to install or uninstall, you can do nothing from within the MSI UI besides cancel or proceed with the install. MSP sequencing is determined long before the UI even has a change to run and is immutable for the remainder of the installation.

@Heath.....can we detect existence(installed or uninstalled) of another patchB from patchA using these property...u just described.....

If yes, how and where we can apply it.....I think 'control action inside msi" can do that.

I reached you through mail also....and I described my question there more clarified.

@Prashant, I don't understand your question. Can you clarify?
