Arc b580 installer.exe problem

[Nana1]

Hi.

I recently tried to install Arc b580 newest driver (ver .8247) after uninstalling the previous version (8132) with DDU, and the installer needed .NET Desktop Runtime (architecture: x64, host version: 9.0.3) to be installed first. The links in the pop up message to download the needed .net version didn't work (image is attached below).

Í tried to install the previous driver versions as well (8135 and 8136), but the same issue occured. I never had this issue with the installer before and the DDU method usually works when newer version needs to be installed.

I also just recently updated my AMD chipset driver to newest version as provided in the manufacturer's site (7.06.24.2226) and updated Windows 11 64bit from version 24H2 to 25H2 before trying to install Arc driver and ran into this problem. 

BIOS is the newest version (v1R3), and I also have these .net versions installed (8.0.17, 9.0.5, and 9.0.7). 

Your help would be much appreciated.

Thanks.

Try this fix

1. Grab the .NET 9.0.3 Desktop Runtime (x64) manually.
   Go here → https://dotnet.microsoft.com/en-us/download/dotnet/9.0
   Scroll down and grab the Desktop Runtime 9.0.3 (x64) version — yes, even though newer ones exist.

2. Repair your existing .NET runtimes just to be safe.

   • Open Settings → Apps → Installed apps.

   • Search “.NET”.

   • For each one, click the three dots → Modify → Repair.

3. Restart your PC after that.

4. Run the Arc installer again as admin.

   • Right-click → Run as administrator.

   • If it still complains, open PowerShell and type:

     dotnet --list-runtimes

     Make sure you see Microsoft.WindowsDesktop.App 9.0.3 listed there.

5. Still no luck?

   • Extract the driver with 7-Zip.

   • Open Device Manager → Display adapters → Update driver → Browse my computer → Have disk and point it to the “Graphics” folder inside the extracted files.
