.net - Unable to uninstall an Assembly from GAC?

Question

I am unable to uninstall an Assembly (log4net.dll) from GAC. It is giving following error.

"Assembly is required by one or more applications".

However if I search the Assembly using ProcessExplorer nothing comes up? How can I remove this Assembly from GAC?

Have you considered reading this KB article and trying it out?

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To work around this problem, examine the list of values for the following subkeys in Registry Editor:

HKEY_CURRENT_USERSoftwareMicrosoftInstallerAssembliesGlobal HKEY_LOCAL_MACHINESoftwareClassesInstallerAssembliesGlobal

If the value for the entry is a Windows Installer descriptor, delete the entry. For example, the value might be a cryptic REG_MULTI_SZ entry that resembles the following: =ysgSC6wx9uiD1dqmmjW>m$!GP^D'A@?z}gn3}lta

Note You must delete the entry. Do not just clear the value of the entry.
