I have installed a DLL using the gacutil.

gacutil.exe /i SI.ArchiveService.CommonLogic.Exceptions.dll

Using the gacutil /l shows that it is indeed installed.

SI.ArchiveService.CommonLogic.Exceptions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=925c8734ae397609, processorArchitecture=MSIL

Then I wanted to uninstall it.

gacutil.exe /u SI.ArchiveService.CommonLogic.Exceptions.dll
Microsoft (R) .NET Global Assembly Cache Utility.  Version 3.5.30729.1
Copyright (c) Microsoft Corporation.  All rights reserved.

No assemblies found matching: SI.ArchiveService.CommonLogic.Exceptions.dll
Number of assemblies uninstalled = 0
Number of failures = 0

Why doesn't this work? How do I uninstall it?

Installing an assembly requires the path name of the DLL. Uninstalling requires the display name of the assembly. They don't have to resemble each other. Review the Assembly.FullName property. gacutil.exe /l (ell as in list) gets you a list of display names.
