You can fix the servicemodelregai.dll error without downloading anything by repairing your .NET Framework installation. This error typically happens when Windows Communication Foundation (WCF) registration files become corrupted.

Press the Windows Key.
Type cmd.
Right-click Command Prompt.
Select Run as administrator.
Copy and paste the following command based on your system, then press Enter:

For 64-bit Windows:

"%windir%\Microsoft.NET\Framework64\v4.0.30319\ServiceModelReg.exe" -r

For 32-bit Windows:

"%windir%\Microsoft.NET\Framework\v4.0.30319\ServiceModelReg.exe" -r

Open Command Prompt as an administrator.

Type the following command and press Enter:

DISM.exe /Online /Cleanup-image /Restorehealth

Wait for the process to hit 100%.
Next, type this command and press Enter:
```
sfc /scannow
```
Restart your computer after the scan finishes.

Method 3: Re-enable .NET Framework Features
