module machine type 'X86' conflicts with target machine type 'x64'

Right click on project->properties->configuration manager button-> Active solution configuration Make sure that if you are using a 32 bit machine, then solution configuration is x86 and if you are using 64 bit, then it shud' be x64 :)

Hi My machine is 32bit windows xp. I have done done configuration x64 in Active solution configuration earlier. but still i am getting same error Regards Gopal

[theCPkid]

for 32 bit, your platform should be x86. make sure to set it as active. if you still get the above error, then good luck! :)

There's another option properties->configuration properties ->Linker->Advanced->Target Machine. :)

Hi I changed Target machine into MachineX64 (/MACHINE:X64). even then still i am getting error. Any thing needs to upgrade for 64bit

[theCPkid]

Try changing to x86 everywhere. :)

[Gopal_Kanchana]

if change into x86 build works. but i want to build it as 64bit

[theCPkid]

now that's an interesting piece of information. AFAIK, module machine type is the one mentioned in the active solution configuration and target machine type inside linker options. if they do not match, then I get the same error as mentioned by you.

[Gopal_Kanchana]

In my system active solution configuration ->Release,Platform->x64 and target machine ->MachineX64 (/MACHINE:X64). every thing is same but why it's not building

[barryboy]

check ure static linking.....the .lib files may be of x86 and the dll u use might be a 64 bit..

Make sure every occurence of .\Release in the x64 properties is set to .\x64\Release. This seems to be a problem with projects converted from older versions of Visual Studio. At least this worked for me...

Hi I faced the same problem. I assume the following in your case. 1 The module that your are building is a 64 bit binary. 2 You are trying to link your module with a 64 bit library. If above is the case, then you need to define an x64 Platform using the Configuration manager. Select the New option. In my case above was the problem and after defining a new configuration for x64, the problem is solved. Regards Nisam
