If a program is made of .NET Framework 4.5 and your Windows doesn’t have it, it won’t run and will show errors. In most cases, running Windows Update should be able to install all including the latest version of .NET Framework for your Windows. However, if it doesn’t install it, here’s how to download .NET Framework 4.5 for Windows 11/10 and Windows 7 64-bit or 32-bit.

If you are using Windows 11 or Windows 10, you should be able to get .NET Framework 4.5 and up to latest version from Windows Update. However, if your programs still ask for .NET 4.5, here’s what you can download and install.
The Microsoft .NET Framework 4.5 was designed for Windows 7, 8 and older. The installer will not work on a Windows 10 system. Thus, instead of getting 4.5, you should install .NET Framework 4.7 which also includes .NET Framework 4, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, and 4.6.2. It’s basically an all-in-one .NET that includes every version ever released in version 4. You can download .NET 4.7 from here.
For Windows 7 users, Windows Update should also be able to automatically update and install the latest available .NET Framework for your PC. However, if you can’t run Windows Update or the framework just seems to be missing, here’s how to download .NET Framework 4.5 for Windows 7 64-bit or 32-bit.
You can download Microsoft .NET Framework 4.5 offline installer from here (4.5.2). On the download page, select your language, then click on the Download button.

After the installation is completed, restart your computer. Then, retry running the problem software again. If the problem persists, you should check the other aspects of the app or game that causes the issue. DirectX is rarely the cause of a major app’s issue if you are already running Windows 11 or Windows 10.
If an app asks for an older version of dotnet, try to install the latest .NET framework version and it should fixes whatever compatibility issue it has. This is because most Dot NET framework versions are backward compatible.
