Access denied using CVI CopyFile function

[jbaptistemarie]

I want my CVI program to overwrite a dll with a new one in c:\windows\system32. When I call the CopyFile function in my program, the error code 6 is returned which means "Access denied".

Do you know how I could programatically give my program the right to overwrite this dll?

Thanks for your help!

Most likley you might have got just a read permission to the dll only.

I am sorry but this issue was my mistake...

The DLL was simply loaded in memory when my program was trying to overwrite it.
