Powershell Scripts Won't Run

I have the following script that uses PSinfo to gather the software information about a computer and displays it to the screen as output. However it will not run.

I have tired this on two computers, both of which have a 'Remote Signed' execution policy.

Here is the Script:

$computersToQuery = ("Computer1","Computer2","Computer3")

$softwareInventory = @{}
foreach ($computer in $computersToQuery) {
   $psinfoOutput = ./psinfo.exe -s Applications \\$computer

   $foundSoftwareInventory = 0
   $computerName = ""
   foreach ($item in $psinfoOutput) {
      if ($foundSoftwareInventory -eq 1) {
         # Force the results to a string
         # Remove any single quotes which interfere with T-SQL statements
         # Load the result into a hash whereby removing any duplicates
         [string]$softwareInventory[$computerName][$item.Replace("'","")] = ""
      }

      if ($item -like "System information for *") {
         $computerName = $item.Split("\")[2].TrimEnd(":")
      } elseif ($item -eq "Applications:") {
         $foundSoftwareInventory = 1
         $softwareInventory[$computerName] = @{}
      }
   }
}

foreach ($computer in $softwareInventory.Keys) {
   foreach ($softwareItem in $softwareInventory[$computer].Keys) {
      $computer + ":" + $softwareItem
   }
}

Are there any error messages?
Is this a script you have downloaded directly from the internet? If so, the script will be blocked from running. Right click the script and select Properites, on the General tab in the bottom right corner will be an Unblock button. Click the button and click OK. The script should now run. If this is the problem.

If it gives output about the installed software, then it is OK. The psinfo.exe gives some information (header, copyright, etc.) that is considered as errors by PowerShell, but I think we can not do much about that, but modify the 5th line to:
   $psinfoOutput = ./psinfo.exe -s Applications \\$computer 2>$null
This supresses that error-like output.

@AussieClint: I copied and pasted it, so there isn't any 'unblock' on this particular file....but good thought


Here are some error messages, which will probably help narrow it down some...sorry I didn't provide these before:


The term './psinfo.exe' is not recognized as the name of a cmdlet, function, script file, or operable program. Check th
e spelling of the name, or if a path was included, verify that the path is correct and try again.
At C:\Scripts\Software.ps1:5 char:32
+    $psinfoOutput = ./psinfo.exe <<<<  -s Applications \\$computer
    + CategoryInfo          : ObjectNotFound: (./psinfo.exe:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

PS C:\Scripts> software.ps1
The term 'software.ps1' is not recognized as the name of a cmdlet, function, script file, or operable program. Check th
e spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:13
+ software.ps1 <<<<
    + CategoryInfo          : ObjectNotFound: (software.ps1:String) [], CommandNotFoundException

Suggestion [3,General]: The command software.ps1 was not found, but does exist in the current location. Windows PowerShe
ll doesn't load commands from the current location by default. If you trust this command, instead type ".\software.ps1".
 See "get-help about_Command_Precedence" for more details.

./psinfo.exe should be .\psinfo.exe
the command software.ps1 should be .\software.ps1

Looks like its just a syntax issue when running.

Are your AD admin tools letting you down?

Ok, the error is occuring because it cannot find .\psinfo.exe
So, I would changed .\psinfo.exe with the full path to that executeable:
$psinfoOutput = C:\somepath\somefolder\psinfo.exe -s Applications \\$computer
