从Windows服务加载dll

Question

I have a windows service which runs fine locally but on the deployment machine I get this exception:

ERROR   Unable to load DLL 'c://XYX//Something.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)  

However, the dll is there. Not sure what the issue is. Any ideas?

Answer 1

You probably have 1 of 2 problems.

A permissions problem. -- Double check the security context that the service is running is appropriate and that it has the corresct permssions for that directory and file.

You are missing a requiired DLL. The Dependency Walker app is a convenient way to see what other DLL are statically linked with your DLL. If a statically linked DLL cannot be loaded, you will see this error.
