c# - How to remove a dll from the GAC when Gacutil.exe refuses service -

i have old version of enterprise library in gac. resists attempt on life made gacutil.exe claiming following:

microsoft (r) .net global assembly cache utility. version 3.5.30729.1 copyright (c) microsoft corporation. rights reserved.

assembly: microsoft.practices.enterpriselibrary.common, version=4.1.0.0, culture=neutral, publickeytoken=e44a2bc38ed2c13c, processorarchitecture=msil
unable uninstall: assembly required 1 or more applications
pending references:
scheme: <windows_installer> id: <msi> description : <windows installer>
number of assemblies uninstalled = 0 number of failures = 0

i found explanation on subject here, can’t find relevant registry keys.

so want nuclear option. got one?

have tried this? may work since don't think it's using gacutil:

using windows interface

navigate gac, located @ %systemdrive%\windows\assembly.

right-click each assembly file included in application, click uninstall, , click yes confirm.
