Custom Facts for windows with powershell

[Harish Kothuri]

Hi, 

I'm trying to create a custom fact to get the installed software using powershell command in windows as follows...

PS Command:- 

Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | where{$_.DisplayName -and $_.displayname -notmatch 'Update'} | Select-Object DisplayName, DisplayVersion | ForEach-Object {Write-Host $_.DisplayName"="$_.DisplayVersion}

Output:-

7-Zip 15.14 = 15.14

ActiveState ActiveTcl 8.4.20.0 = 8.4.20.0

Microsoft .NET Framework 4 Client Profile = 4.0.30319

Microsoft .NET Framework 4 Extended = 4.0.30319

Notepad++ = 6.9.1

Microsoft .NET Framework 4 Extended = 4.0.30319

Puppet = 3.8.7

Microsoft Visual C++ 2012 Redistributable (x86) - 11.0.61030 = 11.0.61030.0

Microsoft .NET Framework 4 Client Profile = 4.0.30319

MSXML 4.0 SP2 Parser and SDK = 4.20.9818.0

Microsoft Visual C++ 2008 Redistributable - x86 9.0.30729.17 = 9.0.30729

VC9.0 SP0 Debug CRT DLLs = 1.0.0

Microsoft Visual C++ 2012 x86 Additional Runtime - 11.0.61030 = 11.0.61030

Microsoft Visual C++ 2012 x86 Minimum Runtime - 11.0.61030 = 11.0.61030

Microsoft Visual C++ 2010  x86 Redistributable - 10.0.40219 = 10.0.40219

ActivePerl 5.16.3 Build 1603 = 5.16.1603

i have created a powershellscript like  getinstalledlist.ps1 with above command and placed in facters.d folder. 

When i run puppet agent -t , i get the following error.

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Failed to parse inline template: `@7_zip_15_14 . 

Can someone help me to get this going?

Thanks & Regards,

Hi Harish,

I am new to powershell and would like t help you although I am new to puppet itself.

In your powershell command why are you looking for registry key 'Uninstall' should it be Installed?

Please advise.

Thanks

Jim

Hi Harish,

I tried to do a simulation at my end and it might be because of syntax error. Please provide some feedback.

Regards,

Jim

Hi Harish!

This fact looks really interesting. I'm interested in doing the same thing in my environment. Did you solve the problem? And if so, do you care to share your solution?

Regards,

Hello All,

Everything works fine after removing 7-Zip software. Looks like highphen (-) is having a problem in the name. You can also use regex to avoid those.

Thanks

Hi Jim,

As what i understand from the command and the registry in windows, Uninstall section list all software's which can be uninstalled - which is nothing but installed software's.

Thanks for clarifying!

I changed it to include the regexp fix:

Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | where{$_.DisplayName -and $_.displayname -notmatch 'Update'} | Select-Object DisplayName, DisplayVersion | ForEach-Object {$factName = $_.DisplayName -replace '-', '_'; $version = $_.DisplayVersion; Write-Host $factName"="$version}
