registry - WiX Bundle bal:condition - util:RegistrySearch - Not working -


a similar post here cant mine working wix bundle bal:condition - util:registrysearch variable false

sir, struggling exact thing working. "version" set 0 when registry key absent , 1 when key present. either cases bundle still gets installed.

i using vs 2015 , wix 3.10. pls can help. 

<wix xmlns="http://schemas.microsoft.com/wix/2006/wi"  xmlns:util="http://schemas.microsoft.com/wix/utilextension"  xmlns:bal="http://schemas.microsoft.com/wix/balextension">    <bundle name="xxx"       version="xxx"       manufacturer="xxx"       upgradecode="xxx"       iconsourcefile="xxx"       copyright="xxx" >  <util:registrysearchref id='searchformyins' />  <bootstrapperapplicationref id="managedbootstrapperapplicationhost">   ... </bootstrapperapplicationref>  <chain>   <packagegroupref id='netfx40web' />    <msipackage sourcefile="$(var.dummyinstaller.targetdir)\dummyinstaller.msi"  displayname="dummy conditioning" />       </chain> </bundle>  <fragment> <util:registrysearch       id='searchformyinst'       variable="version"       result="exists"       root="hklm"       key="software\myinst"        win64="yes" /> <bal:condition message="thirdparty application required.">version</bal:condition> </fragment>  </wix>

the reason installing 

<bal:condition message="messagehere">version</bal:condition>

will evaluate existance of version not value of version. since registry search on exists, version always defined , condition passes. (i believe because registry search variables implicitly string variables)

if add "version = 1" installation should continue when registry search find you're looking for.

i point out particularly nasty pitfall of type of condition. happens if user installs bundle decides don't need bundle or third party program anymore , uninstall them both uninstall third party program first?

your installer unable uninstall because when tries run fail bal:condition every time since third party program no longer present on system.

to solve behaviour should add "or wixbundleinstalled" bal:condition.
