When you install a program that uses .NET Framework, the following error message may appear:<\/p>\n

.NET Framework initialization Error\n\nPlease set registry key \nHKLM\\SOFTWARE\\Microsoft\\.NETFramework\\InstallRoot  to\npoint to the .NET Framework installation<\/pre>\n
\".NET<\/p>\n
Running the .NET Framework Repair tool or removing and reinstalling .NET Framework may not resolve the error.<\/p>\n
Cause<\/h2>\n
The above error occurs due to the missing InstallRoot<\/strong> registry value in one or both of the following keys:<\/p>\n
\nHKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\.NETFramework\nHKEY_LOCAL_MACHINE\\SOFTWARE\\WOW6432Node\\Microsoft\\.NETFramework\n<\/pre>\n
Resolution<\/h2>\n
To fix the .NET Framework initialization Error, please create the missing values in the registry.<\/p>\n
Option 1: Use the REG file to restore the missing values<\/h3>\n
To restore the InstallRoot registry values, download and run netfx_installroot_fix.reg<\/a> (zipped)<\/p>\n
Unzip and run the enclosed REG file.<\/p>\n
Click Yes to confirm.<\/p>\n
\n
Option 2: Create the values manually<\/h3>\n
    \n
  1. Launch Regedit.exe and go to:\n
    HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\.NETFramework<\/pre>\n<\/li>\n
  2. In the right pane, create a new string value (REG_SZ) named InstallRoot<\/strong> (if it doesn’t already exist.)<\/li>\n
  3. Set the value data of InstallRoot<\/strong> to C:\\Windows\\Microsoft.NET\\Framework64\\<\/strong><\/li>\n
  4. Next, go to the following branch:\n
    HKEY_LOCAL_MACHINE\\SOFTWARE\\WOW6432Node\\Microsoft\\.NETFramework<\/pre>\n<\/li>\n
  5. In the right pane, create a new string value (REG_SZ) named InstallRoot<\/strong> (if it doesn’t already exist.)<\/li>\n
  6. Set the value data of InstallRoot<\/strong>  to C:\\Windows\\Microsoft.NET\\Framework\\<\/strong><\/li>\n
  7. Exit the Registry Editor.<\/li>\n<\/ol>\n
    Note:<\/strong> The 2nd location above (i.e., the WOW6432Node branch) doesn’t exist if you’re using Windows 10\/11 32-bit edition. In that case, skip the 2nd location. To determine if you’re using 32-bit or 64-bit edition, see this article How to Find Your Windows 10\/11 Build Number, Version, Edition and Bitness<\/a>.<\/p>\n
