Use this script to detect installed .NET versions on a remote server using WMI. Requires credentials and a computername.
- param ( $Credential, $ComputerName )
- # The official way to detect .NET versions is to look at their known location on the hard drive as per
- # this article: http://msdn.microsoft.com/en-us/kb/kb00318785.aspx
- # thanks to David M (http://twitter.com/makovec) for the WQL
- $query = "select name from win32_directory where name like 'c:\\windows\\microsoft.net\\framework\\v%'"
- $res = Get-WmiObject -query $query -Credential $Credential -ComputerName $ComputerName | ForEach-Object {
- Split-Path $_.name -Leaf } | # returns directories
- Where-Object { $_ -like 'v*' } | # only include those that start with v
- ForEach-Object { [system.version]( $_ -replace "^v" ) } # remove "v" from the string and convert to version object
- # Create hashtable with computername and version details
- $prop = @{
- ComputerName = $ComputerName
- V1Present = &{ if ( $res | Where-Object { $_.Major -eq 1 -and $_.Minor -eq 0 } ) { $true } }
- V1_1Present = &{ if ( $res | Where-Object { $_.Major -eq 1 -and $_.Minor -eq 1 } ) { $true } }
- V2Present = &{ if ( $res | Where-Object { $_.Major -eq 2 -and $_.Minor -eq 0 } ) { $true } }
- V3_5Present = &{ if ( $res | Where-Object { $_.Major -eq 3 -and $_.Minor -eq 5 } ) { $true } }
- VersionDetails = $res
- }
- # Create and output PSobject using hashtable
