Description
Use this function to install the helper DLL to the system. Once installed, the driver is loaded and used by Windows Explorer automatically. ProductName is used to distinguish between installations of the helper DLL made by different applications and to prevent the situation when the helper DLL is installed by two applications and further deinstallation of one of them removes the helper DLL.

Install the correct helper DLLs:
On 64-bit systems you must install 64-bit helper DLLs. 32-bit helper DLLs won't work there.
The installer DLL automatically determines if the system is 32-bit or 64-bit, but you need to have a 64-bit helper DLLs ready for installation.
