.....then do what it says and install .NET 64-bit?

well I left that part out because it goes without saying that would have been the first thing to try. But even though I have it downloaded it’s not acting like it and I’m not that tech savvy. I’m wondering if maybe I have to move .NET into a different folder or something? I found a wired alternative solution but DS4 was nice for the time.

You need the Desktop version of the .net runtime, which probably is this version. If you already have it installed try reinstalling it.

As Kanuan pointed out this problem is often because of users installing either 32bit x86 version of .NET runtime libaries or just the consoleApps or serverApps version of .NET 5.x libraries.

• Forget those 32bit x86 versions of DS4Windows app, ViGem driver and .NET libraries. Download and install 64bit X64 file versions (ie. the installation package has X64 tag).
• From .NET 5.x runtime libraries you need to download the "for DESKTOP apps" version and not console/serverApps version.

In 99.99999999% cases the error msg shown is because of those two mistakes.

closed as inactive and the problem was probably user installing wrong version of .NET libraries
