Final answer:
To install DLL files on Windows 10 64-bit, place 64-bit DLL files in the SysWOW64 folder.
Step-by-step explanation:
To install DLL files on Windows 10 64-bit, you need to place them in the correct location within the operating system. The standard location for DLL files is the System32 folder, which is located in the Windows folder. However, for 64-bit DLL files, you should place them in the SysWOW64 folder, also located in the Windows folder. This is because 64-bit versions of Windows have two different Program Files folders: one for 32-bit applications and one for 64-bit applications.
So, to summarize, for Windows 10 64-bit, place 64-bit DLL files in the SysWOW64 folder.
However, it's worth mentioning that before placing DLL files in the system folders, it's recommended to follow the installation instructions provided by the software or program that requires the DLL files, as some programs may have specific installation requirements for DLL files.
