How to Download and Install rt-usb.dll 64 bit on Windows
If you are a Windows user, you might have encountered DLL files at some point. These files are essential for many programs to run properly, as they contain code and resources that can be shared by multiple applications. However, sometimes these files can go missing, get corrupted, or cause errors that prevent you from using your software. In this article, we will explain what a DLL file is, what rt-usb.dll does, why you might need to download it, how to do it safely, how to install it correctly, and how to fix any problems that might arise.
What Is a DLL File and Why It Is Important
A DLL file, short for Dynamic Link Library, is a type of file that contains instructions that other programs can call upon to do certain things. This way, several programs can share the abilities programmed into a single file, and even do so simultaneously. For example, several different programs might all call upon the veryuseful.dll file (that's made that up, of course) to find the free space on a hard drive, locate a file in a particular directory, and print a test page to the default printer.

Unlike executable programs, like those with the EXE file extension, DLL files can't be run directly but instead must be called upon by other code that is already running. However, DLLs are in the same format as EXEs and some may even use the .EXE file extension. While most Dynamic Link Libraries end in the file extension .DLL, others may use .OCX, .CPL, or .DRV.
DLL files are useful because they can allow a program to separate its different components into unique modules which can then be added or removed to include or exclude certain functionalities. When the software works this way with DLLs, the program can use less memory because it doesn't need to load everything at once. Also, DLLs provide a way for parts of a program to be updated without having to rebuild or reinstall the entire program all over.
What Is rt-usb.dll and What Does It Do
One of the DLL files that you might encounter is rt-usb.dll. This file belongs to Ross-Tech LLC, a company that develops diagnostic software and hardware for Volkswagen Group vehicles. The file name stands for RT-USB library, which means that it contains functions and data related to USB communication between your PC and your vehicle.
The rt-usb.dll file is used by various programs that work with Ross-Tech interfaces, such as VCDS (VAG-COM Diagnostic System), VCP (VAG CAN PRO), HEX-NET, HEX-V2, HEX+CAN, KII-USB, TWIN-USB, and others. These programs allow you to access and modify various parameters and settings of your vehicle's electronic systems, such as engine, transmission, airbag, ABS, steering, etc.
If you have one of these programs installed on your PC, you might need the rt-usb.dll file to make them work properly. Without this file, you might not be able to connect to your vehicle or perform certain functions. You might also see error messages like "rt-usb.dll is missing" or "rt-usb.dll not found" when you try to run the program.
Why You Might Need to Download rt-usb.dll 64 bit
If you have a 64-bit version of Windows, you might need to download the 64-bit version of rt-usb.dll. This is because 64-bit programs can only use 64-bit DLLs, and 32-bit programs can only use 32-bit DLLs. If you try to use a mismatched DLL, you might encounter compatibility issues or errors.
However, not all programs are available in both 32-bit and 64-bit versions. Some programs are only designed for 32-bit systems, and some are only designed for 64-bit systems. In that case, you need to download the corresponding version of rt-usb.dll that matches the program's architecture.
For example, if you have VCDS 21.3.0, which is a 64-bit program, you need to download the 64-bit version of rt-usb.dll. If you have VCDS-Lite 1.2, which is a 32-bit program, you need to download the 32-bit version of rt-usb.dll. You can check the program's architecture by right-clicking on its executable file and selecting Properties > Compatibility > Run this program in compatibility mode for.

How to Install rt-usb.dll 64 bit
After downloading rt-usb.dll 64 bit from either source, you need to install it on your PC. There are two main ways to install rt-usb.dll 64 bit: by copying the file to the program directory or system directory, or by using the LoadLibrary or GetProcAddress functions to load the DLL. We will explain both methods and their pros and cons below.
How to Copy the File to the Program Directory or System Directory
One of the easiest ways to install rt-usb.dll 64 bit is by copying the file to the program directory or system directory. The program directory is the folder where the executable file of the program that uses rt-usb.dll is located. The system directory is the folder where Windows stores its essential files, such as C:\Windows\System32 or C:\Windows\SysWOW64.
By copying rt-usb.dll 64 bit to the program directory or system directory, you can make sure that the program can find and access the file when it needs it. However, this method has some drawbacks and risks that you should be aware of before using it.
First of all, copying rt-usb.dll 64 bit to the program directory or system directory may not work for all programs. Some programs may have a different way of locating and loading DLL files, and they may not recognize the file if it is not in the expected place. You may need to check the documentation or support of the program to see if this method is suitable for it.
Secondly, copying rt-usb.dll 64 bit to the system directory may cause conflicts or errors with other programs that use the same file name. If you have more than one version of rt-usb.dll on your PC, Windows may not be able to tell which one is the correct one for each program. You may end up loading a wrong, outdated, or incompatible version of rt-usb.dll that could cause more problems than it solves.
If you still want to copy rt-usb.dll 64 bit to the program directory or system directory, follow these steps:
Unzip the RT_USB_64.zip file that you downloaded from either source.
Locate the rt-usb.dll file inside the unzipped folder.
Right-click on the rt-usb.dll file and select Copy.
Navigate to the program directory or system directory where you want to paste the file.
Right-click on an empty space and select Paste.
You may need to have administrator privileges to copy files to certain directories. You may also need to overwrite or rename any existing files with the same name.
How to Use the LoadLibrary or GetProcAddress Functions to Load the DLL
Another way to install rt-usb.dll 64 bit is by using the LoadLibrary or GetProcAddress functions to load the DLL. These are functions that are provided by Windows that allow you to load and use DLL files dynamically at runtime. This means that you don't need to copy or register the DLL file beforehand, but instead you can load it when you need it and unload it when you don't.
By using the LoadLibrary or GetProcAddress functions to load rt-usb.dll 64 bit, you can avoid some of the drawbacks and risks of copying the file to the program directory or system directory. You can also have more control over which version and location of rt-usb.dll you want to use for each program. However, this method requires some programming skills and knowledge, and it may not work for all programs.
To use this method, you need to write a code snippet that calls the LoadLibrary or GetProcAddress functions and passes the path and name of rt-usb.dll as parameters. You also need to declare the functions and variables that you want to use from rt-usb.dll and assign them to the pointers returned by the GetProcAddress function. You can write this code in any programming language that supports calling Windows API functions, such as C, C++, C#, Visual Basic, or Python.
For example, if you want to use the RT_USB_OpenPort function from rt-usb.dll, which opens a USB port for communication with a Ross-Tech interface, you can write something like this in C:
// Declare the function pointer type typedef int (__stdcall *RT_USB_OpenPort_t)(int PortNumber); // Declare the function pointer variable RT_USB_OpenPort_t RT_USB_OpenPort; // Declare the DLL handle variable HMODULE hDLL; // Load the DLL file hDLL = LoadLibrary("C:\\Path\\To\\rt-usb.dll"); // Check if the DLL file is loaded if (hDLL != NULL) // Get the address of the function RT_USB_OpenPort = (RT_USB_OpenPort_t)GetProcAddress(hDLL, "RT_USB_OpenPort"); // Check if the function is found if (RT_USB_OpenPort != NULL) // Call the function with a port number int result = RT_USB_OpenPort(1); // Check the result if (result == 0) // The port is opened successfully printf("The port is opened successfully.\n"); else // The port is not opened printf("The port is not opened.\n"); else // The function is not found printf("The function is not found.\n"); // Free the DLL file FreeLibrary(hDLL); else // The DLL file is not loaded printf("The DLL file is not loaded.\n");
