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.

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.
Thanks for your input,
Marc

I'm a little confused by the comment about ProductSearch, sorry.
- ProductSearch: requires a product code which I cannot use
The wix:ProductSearch for use in authoring an MSI takes
ProductSearch/@UpgradeCode as the input.
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.
