Quarantine an .exe for 32 Bit but not 64 Bit

Hi,

We have a problem with the 32 bit computers. We have an application on windows mobile 6.0. when we run on 64 bit machine with symantec it works but when we run on 32 bit machine with symantec it does not work and it takes the exe to quarantine area and delete the original one. 

The symantec version 12.1.6 (12.1.RU6 MP5) Build 7004 (12.1.7004.6500)

What will the problem and solution. Is there anybody who have lived the same problem and somehow solved. We will be gratefull. Thanks.
