A detailed description of my problem,
Himself wrote a 64 - bit DLL files, encapsulates some clients use socket function, did not involve hardware or sensitive operations, is for 64, Excel VBA call on win7_64 + Excel2010_64 platform before running normally,
Recently changed a new computer, is win10_64 + Excel2010_64, VBA call DLL file, the prompt can not find the DLL file, but I confirm many times, the DLL file is in the place of it, the folder does not contain full Angle or Chinese characters, the path is not long, the local hard disk, no access restrictions,
The DLL in order to adapt to both 32-bit and 64 - bit Excel, separately compiled into both 32-bit and 64 - bit version, also useful before win10_64 + Excel2010_32, call the 32-bit version of DLL is also normal,

Can you tell me what's the solution?
