How to Find the Version of .NET Framework Installed on Your System
Knowing which version of .NET Framework is running on your machine matters more than most people realize. It affects whether software installs correctly, whether applications run or crash, and whether your system meets the requirements for tools you rely on every day. The good news: finding this information is straightforward once you know where to look.
What Is .NET Framework and Why Does the Version Matter?
.NET Framework is a software development platform built by Microsoft. It provides the runtime environment and libraries that countless Windows applications depend on to function. When a program is built targeting a specific .NET version, it needs that version — or a compatible one — to be present on the machine running it.
Microsoft has released numerous versions over the years, from the early 1.0 and 1.1 releases through to 4.x, which remains the dominant branch on Windows. Versions in the 4.x family are largely backward-compatible, meaning a machine with .NET 4.8 can typically run apps built for 4.0, 4.5, or 4.6. Earlier versions like 2.0 or 3.5 are separate installs and don't overlap in the same way.
Understanding which version is installed helps you troubleshoot errors, verify software compatibility before installing, and determine whether an update or additional install is needed.
Method 1: Check via the Registry Editor 🔍
The most reliable way to see every version of .NET Framework installed is through the Windows Registry.
- Press Windows + R, type regedit, and press Enter
- Navigate to: HKEY_LOCAL_MACHINESOFTWAREMicrosoftNET Framework SetupNDP
- Expand the subkeys — each folder represents an installed .NET version
- For .NET 4.5 and later, go deeper into the v4 > Full key and look for the Release DWORD value
The Release value is a numeric code that maps to a specific version:
| Release Value | .NET Framework Version |
|---|---|
| 378389 | 4.5 |
| 379893 | 4.5.2 |
| 393295 | 4.6 |
| 394802 | 4.6.2 |
| 460798 | 4.7 |
| 461808 | 4.7.2 |
| 528040 | 4.8 |
| 533320 | 4.8.1 |
If your Release value is equal to or greater than a listed number, that version is installed.
Method 2: Use PowerShell for a Faster Read
If you're comfortable with the command line, PowerShell gives you a clean, readable output without manually browsing registry folders.
