Installing .NET Framework Developer Pack - How to check if it is already installed?

[aho]

Hi,
my installer needs to install the ".NET Framework 4.7.2 Developer Pack".
Unfortunately there is no predefined prerequiste for the Developer Pack.

If I choose the 'normal' ".NET Framework 4.7.2" from the predefinded prerequisites, there is a condition which searches the registry for this key: HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\Release

How can I check if ".NET Framework 4.7.2 Developer Pack" or newer is already installed?

Bests regards,
Andreas

Hello Andreas,

For instance, you can check one of the following registry entries in order to check if it was installed:

1. HKLM:\SOFTWARE\Microsoft\CurrentVersion\Uninstall\*

2. HKLM:\SOFTWARE\WOW6432Node\Microsoft\CurrentVersion\Uninstall\*

Here is a small PowerShell script which queries those entries:

Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*", "HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*" | Where {$_.DisplayName -like '*.NET*' -and $_.DisplayVersion -like '4.7*'} | Select-Object DisplayName, DisplayVersion

(must be run from an elevated PowerShell shell)

Hope this helps.

Best regards,
