The shared library uses the File element without the KeyPath attribute.
<File Id="CommonLibraryAssembly" DiskId="1" Name="Common.dll"
Source="$(var.TARGETDIR)\Common.dll"/>

Is that shared DLL the keypath of its own component? Do any two files share any
component?

Yes and yes. In addition the shared DLL and all service executables are in the
same directory as well.

The file is identical, including every bit in the version resource (all four
parts of the version number, etc.)?
The file is placed in the exact same directory?

Subject: [WiX-users] Component reference counting & DLL sharing
We have the following "file-in-use" problem.
Five Windows Services are installed on a machine. All services use a shared
DLL. All services have their own MSI.
The shared DLL is authored in its own WIX fragment, which is #included in the
five service WIX files, hence the shared DLLs ComponentId is shared across all
five service MSIs.
The first MSI is installed and the windows service starts up referencing the
shared DLL.
When installing the second service a reboot is required because of a "file in
use" error due to the shared DLL which is locked by the first windows service
which has already started up.
Since the ComponentId is shared, my expectation is that the installer should
merely increment the shared component's reference count, as opposed to
attempting to copy the shared DLL and thereby preventing the file-in-use error.
What should I look at to find the root cause of the file-in-use problem?
Thank you.
