How To Open Sys File

  • Click it to download the file. Open the downloaded SYS file by double-clicking the desktop icon. This will open the file's installation wizard. Follow the prompts to install the file. Because it is not an actual program, there will be fewer steps involved. The installation will begin and will take only a moment.

I try to simply install a .sys file into

What is a sys file and how do I open a sys file? Developed by Microsoft, the SYS file format was designed to store compiled system resources like configuration variables and settings required by Windows and DOS (Disk Operating System) for performing its intended operations.

Once the setup ran, my driver.sys is always installed into

Any idea why?

By default the {win}system32is redirected to {win}SysWOW64 by the OS for 32-bit applications (like Inno Setup).

You can override this using 64bit flag:

64bit: Causes the {sys} constant to map to the 64-bit System directory when used in the Source and DestDir parameters, .. This is the default behavior in a 64-bit mode install.

Or enable 64-bit mode install.

In 64-bit mode:

  • The System32 path returned by the {sys} constant maps to the 64-bit System directory by default when used in the [Dirs], [Files], [InstallDelete], [Run], [UninstallDelete], and [UninstallRun] sections. This is because Setup/Uninstall temporarily disables WOW64 file system redirection when files/directories are accessed by those sections. Elsewhere, System32 and {sys} map to the 32-bit System directory, as is normal in a 32-bit process.

As mentioned is all the references above, you should better use {sys} constant instead of {win}system32:

{sys} The system's System32 directory.

Mafia 3 vehicle upgrades. For example: If you used {sys}CTL3D32.DLL on an entry and the system's Windows System directory is 'C:WINDOWSSYSTEM', Setup or Uninstall will translate it to 'C:WINDOWSSYSTEMCTL3D32.DLL'.

On 64-bit Windows, by default, the System32 path returned by this constant maps to the directory containing 32-bit system files, just like on 32-bit Windows. (This can be overridden by enabling 64-bit mode.)
