Hello All,
I am creating an installer to install extensions to a service. The extensions
are just assemblies and related files that are dropped in the same directory as
the service executable. The service installation does not create any registry
settings to indicate where the service is installed.
Given that, I am retrieving the path to the service executable by inspecting
the registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\vsttagent
And the value
ImagePath
Like this:
<!-- Get the installation location for Visual Studio Team System Load
Agent -->
<Property Id='LOADAGENTSERVICEEXECUTABLE' Value=' '>
<RegistrySearch Id='VstsLoagAgentInstallDir'
Root='HKLM'
Key='SYSTEM\CurrentControlSet\Services\vsttagent'
Name='ImagePath'
Type='file'/>
</Property>
Now, I need to compute the parent directory of the file path retrieved as the
value of the property LOADAGENTSERVICEEXECUTABLE.
Is there a specific way to do this?
Directory search won't work because I would have to search from the root for
all drives, which doesn't seem particularly efficient.
Thanks,
Vijai.
