Hi Schemer,

Thanks for your post!

Based on your gacutil.exe output, I assume that you are using .Net1.1
runtime.

I have done some test regarding your scenairo. I first installed a signed
test assembly "hidetabpage" into the GAC. Then I performed the same steps
as you:

G:\>gacutil -l hidetabpage

Microsoft (R) .NET Global Assembly Cache Utility.  Version 1.1.4322.573
Copyright (C) Microsoft Corporation 1998-2002. All rights reserved.

The Global Assembly Cache contains the following assemblies:
       hidetabpage, Version=1.0.2363.18720, Culture=neutral,
PublicKeyToken=
5ef963a156363, Custom=null

The cache of ngen files contains the following entries:

Number of items = 1

G:\>gacutil -uf "hidetabpage, Version=1.0.2363.18720, Culture=neutral,
Public
Token=83d5ef963a156363, Custom=null"

Microsoft (R) .NET Global Assembly Cache Utility.  Version 1.1.4322.573
Copyright (C) Microsoft Corporation 1998-2002. All rights reserved.

Assembly: hidetabpage, Version=1.0.2363.18720, Culture=neutral,
PublicKeyToke
3d5ef963a156363, Custom=null
Uninstalled: hidetabpage, Version=1.0.2363.18720, Culture=neutral,
PublicKeyT
n=83d5ef963a156363, Custom=null

Number of items uninstalled = 1
Number of failures = 0

It seems that these steps work well on my side.

Have you tried to use view your assembly in "C:\WINDOWS\assembly" directory
and use shell context menu to uninstall it? That is you may right click
your assembly and choose "Uninstall" menu item.

Thanks.

Best regards,
