WIX Bundle bal:condition - util:RegistrySearch variable always true

Question

I want my install to fail if a previous version of the application is already installed.

I am trying to search the UpgradeCode in RegEdit file. The Value Name of the Upgrade Code is "BundleUpgradeCode". However even if there is no entry in regedit the log for the Bootstrap returns condition value as true. I am not sure what is going wrong.

    <util:RegistrySearchRef Id="SearchForInstaller" />

    <util:RegistrySearch Id="VSTORuntimeTest" Root="HKLM" Key="SOFTWARE\Microsoft\VSTO Runtime Setup\v4R\" Value="VSTORFeature_CLR40" Variable="VSTORFeature"/>
    <util:RegistrySearch Id="VSTORuntimeVersionV4R" Root="HKLM" Key="SOFTWARE\Microsoft\VSTO Runtime Setup\v4R\" Value="Version" Variable="VSTORVersionV4R"/>
    <util:RegistrySearch Id="VSTORuntimeVersionV4" Root="HKLM" Key="SOFTWARE\Microsoft\VSTO Runtime Setup\v4R\" Value="Version" Variable="VSTORVersionV4"/>

    <util:RegistrySearch Id="DotNetTest" Root="HKLM" Key="SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Client" Value="Install" Variable="DotNetInstall"/>
    <util:RegistrySearch Id="DotNetVersion" Root="HKLM" Key="SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Client" Value="Version" Variable="DotNetVersion"/>

BundleUpgradeCode variable returns 1 from the RegistrySearch, if the registry entry is available. As per my understood we can consider previous version is installed, if the registry entry is available. In that case you need to set

(BundleUpgradeCode=0) or Not (BundleUpgradeCode=1)

to evaluate the condition false. So that the installer will fails and show the Condition message.

<bal:Condition Message="Another version of this product is already installed. Installation of version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs in Control Panel." >Not (BundleUpgradeCode=1)</bal:Condition>

I suspect your registry search condition is not correct. Why you used the Wow6432Node, since the RegistrySearch has the attribute “Win64”

WIX Bundle bal:condition - util:RegistrySearch variable always true
