Different PATH environment variable for 32bit and 64bit Windows - is it possible?



The path environment variable is an important part of a Windows system, as it determines which directories Windows will look in when looking for executable files. It also determines which directories are accessible through the command line. The path environment variable is different for 32-bit and 64-bit versions of Windows, and it is possible to have different path environment variables for each.

The path environment variable is stored in the registry. On 32-bit versions of Windows, the path environment variable is stored in the registry key HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Environment. On 64-bit versions, the path environment variable is stored in the registry key HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Environment, and a second key, HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Run.

The path environment variable is stored as a string, with each directory path separated by a semicolon. To create two different path environment variables – one for 32-bit and one for 64-bit – you need to edit the registry keys mentioned above.

To edit the path environment variable, you will need to use the Registry Editor. To open the Registry Editor, click Start, type regedit, and press Enter. The Registry Editor will open, and you can navigate to the appropriate registry key. To edit the path environment variable, you will need to double-click the Path value, and then enter the desired directory paths. Make sure that each directory path is separated by a semicolon. Once you have entered the paths, click OK to save your changes.

You should be aware that there are some restrictions on which directory paths can be used. For example, certain system directories can only be used in certain versions of Windows. Also, some applications require that certain directories be included in the path environment variable. Therefore, it is important to research the requirements for any applications that you plan to install before making any changes to the path environment variable.

By creating two different path environment variables – one for 32-bit and one for 64-bit versions of Windows – you can ensure that the correct directories are searched when looking for executable files. This can help to ensure that applications run correctly, and that all of the necessary system files are available. It is also important to be aware of the restrictions on which directory paths can be used, as this can help to prevent any conflicts from occurring.
