To me at least that's not the problem you're describing - that's a restatement of your solution, the implementation of which is to block an MSI install if another product is already installed. Anyway, it looks like you'll need to write code to do this as outlined earlier based on detection of an installed product with that UpgradeCode. Would it be a hardship to move to 3.9 WiX?
If there is way of dealing with your problem by doing it in the MSI with an upgrade element to "onlydetect" the installed product, and have the MSI behave differently then that would be a possible solution, which is why it might help to know the problem your detection of that product is going to solve. --------------- Phil Wilson On Mon, May 18, 2015 at 4:24 PM, Rajesh Nagpal <rnag...@microsoft.com> wrote: > Hi Phil, > > Comments inline for your queries: > /It might help to say why you want to do this and what problem it solves./ > > I need to add a blocking condition based on whether a particular msi is > installed or not and hence I need a way to figure out whether that msi is > installed or not. > > /You don't mention version either except in the subject line, so some > clarification about that might help. / > Not sure which version you are talking about.
