when you try to remove an assembly from the global assembly cache, depending on
how you try to remove the assembly:
- If you try to remove the assembly by using the Microsoft
.NET Framework Configuration tool, you may receive the following error message:
Error: There was an error removing <name of
assembly> - If you try to remove the assembly by using Microsoft
Windows Installer, you may receive the following error message:
Error: Assembly: <name of assembly>,
Version=<version of assembly>, Culture=neutral, PublicKeyToken=<public
key token of assembly>, Custom=null Unable to uninstall: assembly is
required by one or more applications Pending references: SCHEME:
<WINDOWS_INSTALLER> ID: <MSI> DESCRIPTION : <Windows
Installer>
CAUSEThis problem may occur if one or more registry values have
become corrupted.
Both Windows Installer and the .NET Framework
Configuration tool verify whether an assembly is being referenced before they
try to remove an assembly from the global assembly cache. If the registry
indicates that the assembly is not being referenced, the assembly is removed.
If the registry indicates that the assembly is being referenced, the assembly
is not removed and you receive the error message that is appears in the
"Symptoms" section.WORKAROUNDTo work around this problem, you must reset the registry
values that have become corrupted. 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 your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. To reset registry value, follow these steps:
- Click Start, click Run,
type regedit, and then click OK.
- In Registry Editor, locate the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Installer\Assemblies\Global If the entry that is named (Default) contains a Windows Installer
descriptor value, delete this entry. - Locate the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Assemblies\Global If the entry that is named (Default) contains a Windows Installer
descriptor value, delete this entry.
