Hi all!
I have a small problem.
In a Module I would like to test that another module is already
installed.
In the Product I can use the following:
<Product ..
<Property Id='OLD_CORE_IS_INSTALLED'>
<ComponentSearch Id='OldCoreSearch'
Guid='9776c872-dbdf-46bd-9cf3-dc0a786e31a2'/>
</Property>
<Condition Message="Old Fls.Pro.Alm.BE module must be installed.">
OLD_CORE_IS_INSTALLED OR Installed
</Condition>
That will give the error dialog and the install aborts, just as I want.
In a merge module I cannot use the <Condition ....> so I use a custom
action instead
<Module ..
<Property Id='OLD_CORE_IS_INSTALLED'>
<ComponentSearch Id='OldCoreSearch'
Guid='9776c872-dbdf-46bd-9cf3-dc0a786e31a2'/>
</Property>
<CustomAction Id="CA_OLD_CORE_IS_INSTALLED" Error="Old
Fls.Pro.Alm.BE module must be installed." />
<InstallExecuteSequence>
<Custom Action="CA_OLD_CORE_IS_INSTALLED" After="AppSearch"
><![CDATA[NOT OLD_CORE_IS_INSTALLED AND NOT Installed]]></Custom>
</InstallExecuteSequence>
The error dialog comes up, but that is first when the merge module is
installing, NOT as a launch condition!
I have tried to change the After="AppSearch" to some other value, but
without any changes.
Are there any way that I can get the merge module custom action to run
at the same time as the normal condition in the Product?
I'm using WiX 3.0.3907.0.
Regards
Bent
