InstallUtil throws TypeLoadException of AssemblySignatureKeyAttribute

Question

On the development computer there was no error when I used InstallUtil, the service was installed successfully.
I intended to install it on a different computer (it has .Net 4.0 installed), so I copied the following files to the target directory:

• InstallUtil.exe
• InstallUtil.exe.config
• InstallUtilLib.dll

After running the util in admin mode, I get the following exception:

Unhandled Exception: System.TypeLoadException: Could not load type 'System.Reflection.AssemblySignatureKeyAttribute' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. at System.ModuleHandle.ResolveType(RuntimeModule module, Int32 typeToken, Int Ptr* typeInstArgs, Int32 typeInstCount, IntPtr* methodInstArgs, Int32 methodInst Count, ObjectHandleOnStack type) at System.ModuleHandle.ResolveTypeHandleInternal(RuntimeModule module, Int32 typeToken, RuntimeTypeHandle[] typeInstantiationContext, RuntimeTypeHandle[] met hodInstantiationContext) at System.Reflection.RuntimeModule.ResolveType(Int32 metadataToken, Type[] ge nericTypeArguments, Type[] genericMethodArguments) at System.Reflection.CustomAttribute.FilterCustomAttributeRecord(CustomAttrib uteRecord caRecord, MetadataImport scope, Assembly& lastAptcaOkAssembly, Runtime Module decoratedModule, MetadataToken decoratedToken, RuntimeType attributeFilte rType, Boolean mustBeInheritable, Object[] attributes, IList derivedAttributes, RuntimeType& attributeType, IRuntimeMethodInfo& ctor, Boolean& ctorHasParameters , Boolean& isVarArg) at System.Reflection.CustomAttribute.GetCustomAttributes(RuntimeModule decora tedModule, Int32 decoratedMetadataToken, Int32 pcaCount, RuntimeType attributeFi lterType, Boolean mustBeInheritable, IList derivedAttributes, Boolean isDecorate dTargetSecurityTransparent)

It seems that even the InstallUtil can't be started so it can't get to install the service.
What should I check?

Can you try to run "installutil.exe" from the C:\Windows\Microsoft.NET\Framework\v4.0.30319\ or some other relevant folder (inside C:\Windows\Microsoft.NET) ??

I mostly think, the error you see is mostly because of mismatch of .NET versions.
