Windows Notes

System Requirements:

• Windows XP or later
• x86 or ARM-64 processor
• USB 2 or USB 3

The library is called nsdspif.dll

When installing the library, you can put it together with your application or into a proper system folder:

Windows	nsdspif.dll	System folder
x86 32	x86 32	C:\Windows\System32
	x86 64	do not use
	arm 64	do not use
x86 64	x86 32	C:\Windows\SysWOW64
	x86 64	C:\Windows\System32
	arm 64	do not use
arm 64	x86 32	C:\Windows\SysWOW64
	x86 64	do not use
	arm 64	C:\Windows\System32

When installing to the system folder check if the library is already installed. Overwrite the installed library only if the version of the library you are about to install is higher than the version of the already installed library.

The arm_64 library is in ARM64X format and may be used by either ARM64, ARM64EC, or X64 applications.

There is also nsdspif.lib file included. You may need this file during development only, and only if you use a Microsoft VC++ compiler.

When building applications for pure ARM64, use nsdspif.lib from arm_64 folder. When building applications for ARM64EC, use nsdspif.lib from x86_64 folder. In either case, use nsdspif.dll from arm_64 folder.
