Registry key not found for registry search of dotnet core runtime

[radz1]

I am not able to get the registry key for the dotnet core runtime.
Registry key not found. Key = 'SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\x64\sharedfx\Microsoft.NETCore.App\3.1.4'

i am using below code in wxs file:

<util:RegistrySearch Root="HKLM"
Key="SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\x64\sharedfx\Microsoft.NETCore.App\3.1.4"
Result="value"
Variable="NetCore3_x64_Installed"
Win64="no"
Format="raw"
/>

You're doing a 32-bit search (Win64="no") so WOW6432Node will not be part of the path. Remove WOW6432Node or make your search 64-bit.

when i am using the key : SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions\x64\sharedfx\Microsoft.NETCore.App. It recognize as a key but when adding \3.1.4 in the key, it says key not found. pls refer below image for 32-bit registry folder tree.

Actually, my software has prerequisite of having core runtime 3.1.4 and greater till [3.1.10]. I wanted to get the list of core runtime version and validate before proceed with installation. For now I achieved it using below code . I have created individual search for each version and put condition if all returns "1" then proceed installation or abort.

<util:RegistrySearch Root="HKLM" Key="[NetCoreKey]" Result="value" Variable="NetCore3_x64_Installed_314" Win64="no" Format="raw" Value="3.1.4"/>
<util:RegistrySearch Root="HKLM" Key="[NetCoreKey]" Result="value" Variable="NetCore3_x64_Installed_315" Win64="no" Format="raw" Value="3.1.5"/>
<util:RegistrySearch Root="HKLM" Key="[NetCoreKey]" Result="value" Variable="NetCore3_x64_Installed_3110" Win64="no" Format="raw" Value="3.1.10"/>

Pls suggest if any better way to achieve it.

There is not really a better way. We hope to get this functionality built in to v4 - #6257 and #6264.

Hi @rseanhall , does it fix in new version v4. Do we have the better way to check the .net core versions ?

Looking at that image, 3.1.4 is not a Key or a Value, It's a Name. A search for a key by that path should always fail as you wrote it, based on the contents of your registry.

@rseanhall after two years has this functionality been added?
