We made some changes to the MSI installer that was released this year and we
are releasing the SP soon. One of those changes include adding support to
uninstall the patches. For this, we modified some Custom elements in
InstallExecuteSequence table of the MSI generating WXS file. (I am not sure if
these are the same as CustomActions though!)
Anyway, how do we specify in the Patch.wxs that these Custom elements need to
be patched?
For instance, here's the change which says that we should not run this action
when uninstalling the patch -
<Custom Action='_GetServiceState' After='_SetADName'><![CDATA[Installed And
REMOVE<>"ALL" And Not MSIPATCHREMOVE ]]></Custom>
And here's how I listed it in the Patch.wxs -
<PatchFamily Id="AgentPatchFamily" Version="1.0.0.1" Supersede="yes">
<!-- Nothing here as of now -->
<CustomActionRef Id="_GetServiceState "/>
</PatchFamily>
I have also tried this way -
<Fragment>
<InstallExecuteSequence>
<Custom Action="_GetServiceState" After="_SetADName" />
<InstallServices Sequence="5800" />
<DeleteServices Sequence="2000" />
</InstallExecuteSequence>
</Fragment>
However in both the cases, when I generated the patch and applied it to the
release MSI through ORCA, I don't see this change at all! Another similar issue
is with InstallServices and DeleteServices elements of the same
InstallExecuteSequence table.
Can someone tell me if this is the right way to do this?
Thanks,
