I can install via gacutil, but not uninstall the same dll

Question

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?

Answer 1

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.

Answer 2

Nevermind.

gacutil.exe /u SI.ArchiveService.CommonLogic.Exceptions

Did the job. Also navigating to C:\WINDOWS\assembly, right-click on it and then choose uninstall would do it. I figured it out by looking at its properties and the name was without the dll extension.

Answer 3

This is a little safer if you have multiple assemblies with the same display name in the GAC

gactutil.exe /u myDll,Version=1.1.0.0,Culture=en,PublicKeyToken=874e23ab874e23ab
