Rundll32.exe for Windows 7 64-bit: How to Load and Run DLLs



Rundll32.exe Windows 7 64 Bits Download: What You Need to Know




Rundll32.exe is a Windows program that can load and run 32-bit dynamic-link libraries (DLLs). DLLs are files that contain code, data, or resources that can be used by multiple programs. Rundll32.exe allows you to execute functions from a DLL without having to write a separate program.

However, rundll32.exe can also cause problems if it is missing, corrupted, or infected by malware. In this article, we will explain what rundll32.exe is, how to use it on Windows 7 64-bit systems, and how to download and fix rundll32.exe runtime errors.


What is Rundll32.exe and How to Use it on Windows 7 64-bit Systems




Rundll32.exe is a Windows command-line tool that can load and run 32-bit DLLs. It is located in the C:\Windows\System32 folder on 64-bit versions of Windows. You can use rundll32.exe to perform various tasks, such as displaying the printer user interface, changing display settings, or opening Control Panel items.


To use rundll32.exe, you need to know the name of the DLL and the function you want to call. The syntax of the rundll32 command is:


rundll32 <DLLname>, <functionname> [arguments]


For example, to display the printer user interface, you can use the following command:


rundll32 printui.dll,PrintUIEntry


You can also use rundll32.exe to run DLLs that are not located in the System32 folder by specifying the full path of the DLL. For example:


rundll32 C:\Program Files\SomeApp\SomeDLL.dll, SomeFunction


However, not all DLLs can be run by rundll32.exe. The DLL must have a function named DllMain and must export the function you want to call. You can use a tool like Dependency Walker to check if a DLL has these requirements.

How to Run 32-bit and 64-bit DLLs on Windows 7 64-bit with Rundll32.exe




Windows 7 64-bit is a popular operating system that can run both 32-bit and 64-bit applications. However, some applications may require you to run a specific DLL file that is either 32-bit or 64-bit. For example, you may want to run a DLL file that contains a device driver, a plugin, or a configuration tool.


How can you run a DLL file on Windows 7 64-bit? The answer is rundll32.exe. Rundll32.exe is a Windows program that can load and run 32-bit DLLs on Windows 7 64-bit systems. However, it can also run 64-bit DLLs if you use the correct version of rundll32.exe.


As we mentioned earlier, there are two versions of rundll32.exe on Windows 7 64-bit systems:


  • 64-bit: C:\Windows\System32\rundll32.exe



  • 32-bit: C:\Windows\SysWOW64\rundll32.exe



The 64-bit version of rundll32.exe can run both 32-bit and 64-bit DLLs, while the 32-bit version of rundll32.exe can only run 32-bit DLLs. Therefore, if you want to run a 64-bit DLL on Windows 7 64-bit, you need to use the 64-bit version of rundll32.exe. If you want to run a 32-bit DLL on Windows 7 64-bit, you can use either version of rundll32.exe.


To run a DLL file with rundll32.exe, you need to know the name of the DLL and the function you want to call. The syntax of the rundll32 command is:


rundll32 <DLLname>, <functionname> [arguments]


For example, to run a 64-bit DLL named SomeDLL.dll that has a function named SomeFunction, you can use the following command:


C:\Windows\System32\rundll32 SomeDLL.dll, SomeFunction


To run a 32-bit DLL named AnotherDLL.dll that has a function named AnotherFunction, you can use either of the following commands:


C:\Windows\System32\rundll32 AnotherDLL.dll, AnotherFunction


C:\Windows\SysWOW64\rundll32 AnotherDLL.dll, AnotherFunction


You can also specify the full path of the DLL if it is not located in the System32 or SysWOW64 folder. For example:


C:\Windows\System32\rundll32 C:\Program Files\SomeApp\SomeDLL.dll, SomeFunction


C:\Windows\SysWOW64\rundll32 C:\Program Files (x86)\AnotherApp\AnotherDLL.dll, AnotherFunction


Note that some DLLs may require additional arguments to run properly. You can check the documentation of the DLL or use a tool like Dependency Walker to find out the required arguments.


Conclusion




Rundll32.exe is a handy Windows program that can load and run DLL files on Windows 7 64-bit systems. You can use it to run both 32-bit and 64-bit DLLs by using the correct version of rundll32.exe and specifying the name and function of the DLL.
