Powershell - 导出 csv 以获取程序名称、版本、安装日期

Question

im trying to run a command against a list of computers to find out information on the programs on the computers. then i would like to export that information on a Csv in the following format:

Computer name, McAfee Agent, version, Installdate

i wanted to get the list of these computers and the programs version numbers and installdate.

this command works, but not for exporting:

Get-WmiObject win32_product -ComputerName SYSTEMName01 | Where name -Match "McAfee Agent" | Select Name, Version, Installdate

I tried using the following code here, but this isn't working because it populates the information in Powershell then gives me a:

• "RPC server is unavailable" red text.
• and the Exported CSV document only gives me one populated row of the Name of the program and its version # and install date. but it doesn't populate the computer name it looked into and it doesn't list the other computers in the.txt document.

$computers = Get-content -Path "C:\nice\List-of-systems.txt"
Get-WmiObject win32_product -ComputerName $computers | Where name -Match "McAfee Agent" | Select Name, Version, Installdate |
Export-Csv -Path "C:\nice\computers-mcafee-status.csv"

If you're gonna go through the trouble of just querying single information, might as well query the system info a long with it.

<#
SYNTAX
    Get-SystemInfo [[-ComputerName] <string[]>]  [<CommonParameters>]

EXAMPLE
    Get-SystemInfo -ComputerName SystemOne, SystemTwo
    'SystemOne', 'SystemTwo' | Get-SystemInfo
    Get-content -Path "C:\nice\List-of-systems.txt" | Get-SystemInfo
    Get-content -Path "C:\nice\List-of-systems.txt" | Get-SystemInfo | Export-CSV C:\List-Of-Systems.csv -NoTypeInformation

The issue with what you're trying to do is, you're not including the computername to be exported along with the other information. You also need to -Append to the file. The errors you receive mean that you just couldn't connect to the remote machine.
