This error means that our code could not load the module hid.dll using LoadLibrary. This DLL is part of the OS so it will definitely be present.

Find out the extended error - this will give more information (the Windows error as to why the file cannot load).

The extended error 8 from Windows means ERROR_NOT_ENOUGH_MEMORY. i.e. there is not enough memory to complete the command.

The most likely cause of this error is that your code has a memory leak of some kind. These can be difficult to find. Simple tools such as Process Monitor or Task Manager could help you with this.Or maybe your programming language offers a tool to do this?

Although it can occur when there is no memory left this is very rare - it is much more likely to occur when the virtual address space is fragmented. VMMap is a more sophisticated tool that could help you look at this.
