What is the impact of a DLL filepathname stored in the above key.
Does
it have any effect on normal DLL access. Is it put there by any
automatic process or by a utility program.

If a DLL really is to be shared by multiple products, then installers
should mention the DLL in that key so that uninstallers know when it's
safe to delete it. That registry key provides a reference count for
shared DLLs.

You might try RegMon to see whether your program (or the program
starting your program) accesses that key during normal operation. I
doubt it will.

Thanks Rob, RegMon is a good suggestion. I wondered what the value
meant, would that value be specified by the installer , or somehow
generated by the OS when it was accessed.
