Shared DLLs
You can get the information about shared DLL files at the below link.
Shared DLL
When we want to make a dll file as shared in msi, then we need to set the component as Shared.
In Installshield, we have that option when go to the Component section and click on that particular component which holds the dll file.
Then the component Attribute column in the component table of msi will be incremented by 8 to its previous value.
So, whenever you install the msi, it will be added to the below hive in registries and the particular count of number of applications using it will also be available to see there.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDLLs
If we uninstall the msi, the reference count will be decreased.
