Powershell - MSI / EXE version number problem

[tri_94]

Hi there

 

I've got a script to deploy Teams MSI, it currently compares the MSI version with the EXE version installed on the pc and if they don't match will uninstall and then reinstall the correct version.

 

Just trying to tidy up the script really. problem i've got is the exe has both file version and product version.

 

Get-item returns product version.

$LocalVersion = (Get-Item "C:\Program Files (x86)\Teams Installer\Teams.exe").VersionInfo.FileVersion

 

MSi version is 1.3.0.28779 but the exe version is 1.3.00.28779

 

currently I use the following code

 if ($LocalVersion -eq "1.3.00.28779") {$LocalVersion = "1.3.0.28779"

 

I would like to be able to just change the msi and not have to add a new if statement for every version that comes out.

 

Using Orca i've checked to see if the version with two 00's is in the msi properties and its not. So is there a way to tell ignore the second 0 in the version number?

 

Hope this makes sense.

 

Thanks

No need to manipulate the strings, just use the [Version] type accelerator as that will take care of the redundant zeroes:

 

$LocalVersion = [Version](Get-Item "C:\Program Files (x86)\Teams Installer\Teams.exe").VersionInfo.FileVersion

 

You can test it yourself by comparing the two examples you gave:

 

$firstVersion = [Version][color=#333333]"1.3.00.28779"
$secondVersion = [Version][/color][color=#333333]"1.3.0.28779"
$firstVersion -eq $secondVersion[/color]

Thank you for that. It works as you suggested.
