Hi,
I got a problem during uninstall:
Our COM project (build by install shield) and WIX project shared some common
files.
In WIX, during uninstall, I want to check if our COM project is installed
or not through registry.
If COM project is installed, I don’t want to uninstall these shared
component; if not, I want to uninstall these components.
I tried the following code:
<Property Id="COM_INSTALLED">
<RegistrySearch Id="COM_Installed" Key="SOFTWARE\...\Current Version"
Root="HKLM" Type="raw" Win64="$(var.Win64)" />
</Property>
...
<Component Id="File1" Guid="..." DiskId="1" Permanent ="yes"
Transitive ="yes" >
<Condition ></Condition>
<File Id="File_file1" Name="file1.dll"
Source="C:\temp\file1.dll" KeyPath="yes" Checksum="yes"/>
</Component>
<Component Id="File1" Guid="..." DiskId="1" Transitive
="yes" >
<Condition ></Condition>
<File Id="File_file1" Name="file1.dll"
Source="C:\temp\file1.dll" KeyPath="yes" Checksum="yes"/>
</Component>
However, I got error "Duplicate symbol 'Component:File1' found. This
typically means that an Id is duplicated. Check to make sure all your
identifiers of a given type (File, Component, Feature) are unique."
Any idea about how should I make the logic work?
Thanks
Ruth
