If a Component condition has already been evaluated it will not be evaluated again (like in repair) unless the Component is marked Transitive.

Subject: Re: [WiX-users] Registry Manipulation I'll give it a try again as I am obviously missing something. I am specifically referring to reinstall where REINSTALLMODE has option u meaning: Rewrite all required registry entries from the Registry Table that go to the HKEY_CURRENT_USER or HKEY_USERS registry hive. You are saying that, if I condition the component out, this above won't apply to that particular Registry entry/component? -----Original Message----- From: Rob Mensching [mailto:rob.mensch...@microsoft.com] Sent: Monday, February 09, 2009 12:15 PM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Registry Manipulation If you condition out a Component then nothing in that Component should be installed/uninstalled/repaired. -----Original Message----- From: Tony Juricic [mailto:tjuri...@tradestation.com] Sent: Monday, February 09, 2009 08:36 To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Registry Manipulation Would this really work? I ask because I have never managed to get conditions to work for Registry components. In my experience Registry is handled in bulk. All the components (i.e. Registry keys and values) either get created/written or no. -----Original Message----- From: p...@hoaske.dk [mailto:p...@hoaske.dk] Sent: Monday, February 09, 2009 9:39 AM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Registry Manipulation Hi Brian, after doing the RegistrySearch the property "MYREGKEYPROP" will be assigned the value if the key exists. If the key doesn't exist, the property "MYREGKEYPROP" will be assigned the default value "YetNotSet". You can use that fact in the condition for the component that writes/creates the key as explained: Component Id="CreateKeyComponent" Guid="" KeyPath="yes"> <RegistryValue Id="WRITEREGVALUE" Action="write" Key="SOFTWARE\SomeThing\MyKey" Name="RegValueName" Root="HKLM" Type="string" Value="NewValue"/> <Condition>MYREGKEYPROP~="YetNotSet"</Condition> </Component> It should now create the key if the Registry value was not found (Which means "MYREGKEYPROP" was assigned the default value "YetNotSet".
