No installers found when running install util on custom pssnapin

Question

I created a very simple PSSnapin but when I go to run IntallUtil against the assembly I get the following:

No public installers with the RunInstallerAttribute.Yes attribute could be found in the C:\Tools\PowerShellCommands\SetServerDataSource\bin\Debug\SetServerDataSource.dll assembly. Remove InstallState file because there are no installers.

However, I definitely have an installer (inherited from CustomPSSnapIn) with [RunInstaller(true)]:

[RunInstaller(true)]
public class SetServerDataSourcePSSnapIn : CustomPSSnapIn
{
   ///
}

Any ideas?

Answer 1

Be carefull to install it with the good InstallUtil.exe. It exists a 64 bits ans a 32 bits.

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\InstallUtil.exe

Versus

C:\Windows\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe

You may adapt this to the framework in usage in your company. It depends from where you referenced System.Management.Automation . On a 64bit computer if you do it from :

C:\Program Files\Reference Assemblies\Microsoft\WindowsPowerShell\v1.0

Its a 64Bis assembly.

Answer 2

When I've done this, I've just applied [RunInstaller(true)] to the PSSnapIn derived class that defines the snapin.

However, unless you really must support PowerShell V1, it would be better to create a (binary) module and have no need for an installer.
