i create the ActiveX control(.dll) using user control & register as COM component . it working fine in 32 bit OS . but when register the same activeX control in 64 bit os (window server 2008) it throws following exception
Could not load file or assembly 'file :////C:\Program Files\STPL\GlobActiveX.dll' or one of its dependencies. an attempt was made to load a program with an incorrect format. 

i have used the following code to register the dll component
filepath=C:\Program Files \STPL\GlobActiveX.dll
                Assembly asm = Assembly.LoadFrom(filePath);
                RegistrationServices regAsm = new RegistrationServices();
                bool bResult = regAsm.RegisterAssembly(asm, AssemblyRegistrationFlags.SetCodeBase);
