Fileversion issue

PowerShell Help
1

Hi, I’m trying to get this script sorted out but I’m having an issue. No matter what I put for the fileversion to check for it always comes back as “Already Installed”. So if I change the ‘14.2.770.0’ to another value it should come back as “Not Installed”. Any ideas?

 function CheckSepVersion

{

$computername = $env:COMPUTERNAME

$OSArch = Get-WmiObject -Class win32_OperatingSystem -ComputerName $computername | select pscomputername, OSArchitecture

if ($OSArch.OSArchitecture -eq “64-bit”)

{

(Get-Item “C:\Program Files (x86)\Symantec\Symantec Endpoint Protection\smc.exe”).VersionInfo.FileVersion


}

else

{

(Get-Item “C:\Program Files\Symantec\Symantec Endpoint Protection\smc.exe”).VersionInfo.FileVersion


}

}


 


if (CheckSepVersion -eq ‘14.2.770.0’)

{


Write-Output “Already installed”


}

else

{

Write-Output “Not installed”


}

Let’s tweak your code a little bit … (BTW: you should put it between the tags, not after them! :wink: )

function Get-SepVersion{

$computername = $env:COMPUTERNAME

$OSArch = Get-WmiObject -Class win32_OperatingSystem -ComputerName $computername | Select-Object -Property pscomputername, OSArchitecture

if ($OSArch.OSArchitecture -eq “64-bit”){

version.VersionInfo.FileVersion

}

else {

version.VersionInfo.FileVersion

}

}


if (Get-SepVersion -eq [version]‘14.2.770.0’) {

Write-Output “Already installed”

}

else{

Write-Output “Not installed”

}

If you like to compare versions you should cast the numbers as version objects.

Weird. 14 invisible characters at the end?? I guess you can trim it.
