Because PROPERTY <> "" implies the property exists but has no value, but with the Windows Installer Service, the property will be removed if it is empty. Hence, NOT PROPERTY is the test that should be used.

Subject: Re: [WiX-users] Two Mutually Exclusive Products I have a simple condition question: I have my installer working as I need but I need clarification on something, and yes I fully understand this is of the most basic understanding, but it doesn't match what I am reading (probably misunderstanding) in documentation. My WIX Code: <Property Id="OTHERPRODUCTFOUND"> <ProductSearch UpgradeCode="GUID of SOME PRODUCT " Minimum="1.0.0.0" Maximum="99.0.0.0" IncludeMinimum="yes" IncludeMaximum="no" /> </Property> <Condition Message="Other Product Exists, Cannot install this one."> <![CDATA[NOT OTHERPRODUCTFOUND]]> </Condition> Question: The product search runs as expected, my property gets populated with the other products GUID when it exists and does not when it doesn't exist. So I expected my condition to look like this: OTHERPRODUCTFOUND <> "" meaning if not populated with Guid DO NOT display the message. Why does NOT OTHERPRODUCTFOUND evaluate to true when search is successful, in other words my message shows up and vice versa. In code it would do something like this: If (OTHERPRODUCTFOUND == "") // Other product not found Run install as normal Else // Product found DO NOT run install Thanks for helping me clear this simple misunderstanding up.

Subject: Re: [WiX-users] Two Mutually Exclusive Products You are correct: ProductSearch does have an UpgradeCode too, I am using wix 3.8 and the documentation of 3.8 doesn't make reference to the UpgradeCode. I will try using 3.9. I will also investigate (learn) what you mean by implementing code in the ba (???) for the OnDetect handlers.

The util:ProductSearch for use in a bundle takes either a ProductCode or an UpgradeCode (which I think was added in wix 3.9 ). I use a bundle driven msi(s) method and so in a similar situation where I have mutually exclusive 'products' (suites of products). In my situation rather than use a bal:Condition, I implement code in the ba, which is called in the OnDetectXxx handlers to determine if I need to communicate with the user and terminate the setup. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Two-Mutually-E xclusive-Products-tp7598832p7598833.html Sent from the wix-users mailing list archive at Nabble.com. ---------------------------------------------------------------------------- -- New Year.
