Hello,
I am relatively new to WiX. It is a great tool, but I still need some time
to learn it better.
I have encountered a problem with registration and unregistration of a COM
component. I have created installers for two applications, lets call them A
and B. Both are using the same COM component. I have used the heat tool, as
recommended. When installing A or B, the component is registered without any
problems.
But when I install A and B, then remove A (with Add/Remove programs) the COM
class gets unregistered and B cannot use it anymore. Is there a clean
solution to prevent this from happening? I would like to unregister the COM
when BOTH A and B are uninstalled.
My WIX code for COM registration (it is a DirectShow filter):
<Component Id="cropFilter" Guid="{1102C100-D04F-4b57-BB93-78F3F4604988}">
<File Id="filA657AE943D50CC1EAEFA9FFAB5BD3C4E" KeyPath="yes"
Source="COM\CropFilter.dll">
<Class Id="{2E164ADE-2F13-4EE9-BA95-28CF9AE23511}"
Context="InprocServer32" Description="Crop Properties" ThreadingModel="both"
/>
<Class Id="{F5E69199-7AB2-40F0-BFC0-6938430F4F19}"

</File>

Name="FilterData" Value="02000000000020000000000000000000" Type="binary"
Action="write" />
<RegistryValue Root="HKLM"

Name="wheel" Value="1" Type="integer" Action="write" />
</Component>
Any help would be appreciated,
Best regards,
