Powershell / Where arrays
Posted on 2016-09-22
Hi everybody!
I'm trying to get a script to get the version (32 or 64 bits) of different INF drivers and then install the one corresponding to the version of the system.
In this case I've got two INF, one 64 bits, one 32 bits, but instead of returning only one path of the INF (in 64 bits in my case), it returns both!
Can you see what I did wrong?
Thank you in advance,

# GET THE OS VERSION OF THE SYSTEM (64 or 86)
$SYS_OS_VERSION = ((Get-WmiObject Win32_OperatingSystem).OSArchitecture).Substring(0,2)
$RESULT = $INF_PATH | ? {($INF_OS_VERSION -eq $SYS_OS_VERSION)}

I don't see any correlation between $INF_PATH and $INF_OS_VERSION, meaning there's nothing that binds them together, and so your Where-Object comparison has no meaning.
Easiest way to troubleshoot would be if you could provide both .INFs.

Hi,
I attached the *.inf files (I just changed the extension to *.txt or I couldn't upload them).
As you will see, there are actually more datas extracted from the *.inf of the print drivers (the OS, the driver name, the description language)
These files are just for the PS versions of the drivers, but (of course) there are more.
Thank you again for your help,
Johann

$INF_PATH is nowhere dependent on $INF_OS_VERSION or $INF_DESC in the script. The variables are created using the $INF_PATH but not connected to it in Script.
Basically $INF_PATH contains only the list of file names, you can filter based on the multiple properties of the object or even based on the file content...
In following example, I created a PowerShell custom object to connect the file name, OS architecture and Language and finally filtered it based on your requirement.. Try it and see if it works for you.
