Windows 7/8 64-bit systems cannot register a 32-bit DLL file for a solution

A problem has been encountered these days, the following error occurs when running a software that is easily developed by the language. My system is Windows7 64-bit Professional Edition . Look for dm.dllunder System disk Windows/system32. But there is no such file. So I went to Baidu to find relevant answers, asked a lot of people, the answer is the same, I concluded that these are copied to paste to, there is no good answer, some is outrageous crazy. To Baidu know question, also copy paste to, irrelevant.

error message: Cannot load OCX component "version 1.0 Dm1.0", its component or type library file name is "Dm.dll", the digital signature is "{84288aad-ba02-4ee2-85ec-3fad4d11354d} #1.0#0", Make sure that the component has been installed on the Windows system with the following information: OCX component initialization error: Getting interface information for a component or type library has failed

So I think is a lack of dm.dll, I go to the Internet to download Dm.dll, but next to the same registration, said version is not compatible with the online no 64 win7 system dm.dll related download. I've been crazy this time. However, the dead horse as a live horse medicine, the problem placed in the registration Dm.dll file. How to register it? Put him directly to Windows/system32, then run input Windows 7 cannot register Dm.dll file, solution "module" Dm.dll "Loaded, but ...", "module" Dm.dll "Load failed ..." Workaround 1, find C:\Windows\SysWOW64. Copy and paste the Dm.dll (download it online) into this folder.
2. Allow CMD as Administrator. As follows: 3, enter regsvr32 dm.dll return. Registration is successful. The software can also run successfully. The same applies to the WINDOWS8 64-bit system as described above.
