Hi @burakbilgehan,

The 0x8007007E error code general indicates an issue in locating the DLL needed.

I would therefore check your Paths which generally go in the order:

1) Current Directory
2) System folder, C:\windows\system32 or c:\windows\SysWOW64 (for 32-bit process on 64-bit box).
3) Reading from the Path environment variable

In addition I’d check the dependencies of the DLL, the dependency walker provided with Visual Studio can help you out here, it can also be downloaded for free: http://www.dependencywalker.com
