Cannot process argument transformation on parameter 'InstalledModuleInfo'. Cannot convert the "System.Object[]" value of type "System.Object[]" to type "System.Management.Automation.PSModuleInfo"

Install Contoso module to multiple module paths in $env:PSModulePath then install another version using Install-Module instead of Update-Module.

I installed 1.1.2.0 still see this issue when attempting to Install-Module AzureRM.

PackageManagement\Install-Package : Cannot process argument transformation on parameter 'InstalledModuleInfo'. Cannot convert the "System.Object[]" value of type "System.Object[]" to type

Also, at first I had both 1.0.0.1 and 1.1.2.0 installed. When I'd run Install-Module AzureRM, I'd see that 1.0.0.1 was being referenced in the error message. I then forcefully uninstalled 1.0.0.1 using (this):

function Remove-ModuleByVersion
{
    param (
        [Parameter(Mandatory=$true)]
        [string]
        $Module,

        [Parameter(Mandatory=$true)]
        [string]
        $VersionToMatch
    )

    Get-Module $Module | where {([string]($_.Version)).StartsWith($VersionToMatch)} | Remove-Module -Verbose
}

Remove-ModuleByVersion 'PowerShellGet' '1.0.0.1'

After doing removing v1.0.0.1, the error message still occurs, but it now references v1.1.2.0,

After installing v1.1.2.0 of PowerShellGet, I still see this issue when I run Install-Module AzureRM:

PackageManagement\Install-Package : Cannot process argument transformation on parameter 'InstalledModuleInfo'. Cannot convert the "System.Object[]" value of type "System.Object[]" to type 
"System.Management.Automation.PSModuleInfo".
At C:\Program Files\WindowsPowerShell\Modules\PowerShellGet\1.1.2.0\PSModule.psm1:2089 char:20

    + FullyQualifiedErrorId : ParameterArgumentTransformationError,Validate-ModuleAuthenticodeSignature,Microsoft.PowerShell.PackageManagement.Cmdlets.InstallPackage

At first, the error message still referenced v1.0.0.1 of PowerShellGet. I turns out that v1.0.0.1 and v1.1.2.0 were both installed. I uninstalled v1.0.0.1 using this.

function Remove-ModuleByVersion
{
    param (
        [Parameter(Mandatory=$true)]
        [string]
        $Module,

        [Parameter(Mandatory=$true)]
        [string]
        $VersionToMatch
    )

    Get-Module $Module | where {([string]($_.Version)).StartsWith($VersionToMatch)} | Remove-Module -Verbose
}

Remove-ModuleByVersion 'PowerShellGet' '1.0.0.1'

I still get the error message above, but now it references v1.1.2.0 PowerShellGet.

It seems like this issue is still present even after PR #44.

@pauldalyii, could you please provide consistent repro steps to repro this issue on a clean machine?

I ran into this today trying to do Install-Module Azure -AllowClobber -Force on Windows 10 Anniversary (it said Azure 2.1.0 was already installed, hence the Force). The fix a co-worker found which worked for me was to clear out the Azure-related stuff in:

• %ProgramFiles%\WindowsPowerShell\Modules folder
• %ProgramFiles(x86)%\Microsoft SDKs\Azure\PowerShell
