This error can occur for several reasons, including a corrupted registry, incorrect permissions, or missing registry keys. Solving the error requires understanding the root cause and implementing a solution to correct it. In this article, we will provide a list of possible methods to resolve the «RegGetValueW» error in SQL Server.

Method 1: Repair the Registry

If you encounter the «Windows API call «RegGetValueW» returned error code: 0″ error in SQL Server, you can try repairing the registry to fix it. Here are the steps:

1. Press the Windows key + R to open the Run dialog box.

2. Type «regedit» and press Enter to open the Registry Editor.

3. Navigate to the following key:

   HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL Server

4. Right-click on the «Microsoft SQL Server» folder and select «Export» to create a backup of the registry key.

5. Save the backup file to a safe location.

6. Delete the «Microsoft SQL Server» folder from the registry.

7. Restart the SQL Server service.

Here is a sample code:

@echo off

regedit /e C:backup.reg "HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL Server"

reg delete "HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL Server" /f

net stop MSSQLSERVER

net start MSSQLSERVER

This code creates a backup of the «Microsoft SQL Server» registry key, deletes the key, stops and starts the SQL Server service.

Note: Be careful when making changes to the registry. Back up the registry before making any changes.

Method 2: Grant the Correct Permissions

To fix the «Windows API call «RegGetValueW» returned error code: 0″ error in SQL Server, you can grant the correct permissions to the registry key.

Here are the steps to do it:

1. Open the Registry Editor by typing «regedit» in the Start menu search box and pressing Enter.

2. Navigate to the following registry key:

   HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL Server

3. Right-click on the «Microsoft SQL Server» key and select «Permissions».

4. Click the «Add» button, enter the name of the user or group that needs access to the key, and click «OK».

5. Select the user or group from the list, and then check the «Full Control» box under the «Allow» column.

6. Click «OK» to save the changes.

Here is an example of how to grant permissions to the registry key using PowerShell:

$registryKey = "HKLM:SOFTWAREMicrosoftMicrosoft SQL Server"
$user = "DOMAINUSERNAME"
$permission = "FullControl"
$rule = New-Object System.Security.AccessControl.RegistryAccessRule($user,$permission,"Allow")
$acl = Get-Acl $registryKey
$acl.SetAccessRule($rule)
Set-Acl $registryKey $acl

This PowerShell script grants full control to the specified user on the «Microsoft SQL Server» key.

Another way to grant permissions to the registry key is to use the «regini» utility. Here is an example:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL Server [1 5 7 11]

This command grants full control to the «Administrators» group and the «SQLServerMSSQLUser$» group on the «Microsoft SQL Server» key.

By granting the correct permissions to the registry key, you should be able to resolve the «Windows API call «RegGetValueW» returned error code: 0″ error in SQL Server.

Method 3: Check and Re-install the .NET Framework

If you encounter the error message «Windows API call RegGetValueW returned error code: 0» in SQL Server, it may be caused by a corrupted or missing .NET Framework installation. In this case, you can try to fix the issue by checking and re-installing the .NET Framework. Here are the steps:

1. Check the current .NET Framework version installed on your system. You can do this by opening the Command Prompt and running the following command:

reg query "HKLMSOFTWAREMicrosoftNET Framework SetupNDPv4Full" /v version

1. If the output shows that the .NET Framework version is not installed or is corrupted, you can download and install the latest version of .NET Framework from the Microsoft website.

2. After installation, verify that the .NET Framework is installed correctly by running the following command in the Command Prompt:

reg query "HKLMSOFTWAREMicrosoftNET Framework SetupNDPv4Full" /v version

1. If the output shows the correct version of .NET Framework, restart the SQL Server service and check if the issue is resolved.

Here’s an example PowerShell script that checks the .NET Framework version and installs the latest version if it’s missing or corrupted:

$frameworkVersion = (Get-ItemProperty 'HKLM:SOFTWAREMicrosoftNET Framework SetupNDPv4Full').version
if ($frameworkVersion -lt '4.8') {
    Write-Host "Installing .NET Framework 4.8..."
    $webClient = New-Object System.Net.WebClient
    $url = "https://download.visualstudio.microsoft.com/download/pr/014120d7-eb06-4d8e-9d1a-5f5c710f49d3/5e3f7cf834d1f03f5b5f2b5d2dfb9fc2/ndp48-x86-x64-allos-enu.exe"
    $path = "C:Tempndp48-x86-x64-allos-enu.exe"
    $webClient.DownloadFile($url, $path)
    Start-Process $path -ArgumentList "/q /norestart" -Wait
    Write-Host "Installation complete."
}

This script checks if the .NET Framework version is less than 4.8 and downloads and installs the latest version if necessary. Note that this script requires administrative privileges to run.

In conclusion, checking and re-installing the .NET Framework can help fix the «Windows API call RegGetValueW returned error code: 0» issue in SQL Server. Make sure to verify the installation and restart the SQL Server service after installation.
