I used Ubuntu 12.04 64bit

I downloaded Tizen SDK for Wearable 1.0.0 (Ubuntu 64bits / tizen-wearable-sdk-2.2.159_ubuntu64.bin)

after that, changed mod to a+x, When I executed tizen-wearable-sdk-2.2.159_ubuntu64.bin. error happend

error message is 

Cannot execute the installmanager because of bit difference. 
 You must use installmanager which is same as OS bit. 
 Current OS bit : 32 
 Current InstallManager bit : 64 

As I wrote above, my Ubuntu is 64 bit OS

(When I checked using “uname -a”, result is 

Linux XXXXXX 3.8.0-29-generic #42~precise1-Ubuntu SMP Wed Aug 14 16:19:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux )

using “lsb_release -a”

No LSB modules are available.
Distributor ID:    Ubuntu
Description:    Ubuntu 12.04.5 LTS
Release:    12.04
Codename:    precise)

I don’t know what’s going on, what is the problem. who have any Idea ?

(Plus, I also downloaed 32bit Tizen SDK Wearable, tizen-wearable-sdk-2.2.159_ubuntu-32.bin.

When I executed that binary, of course, it didn’t work . The message is 

The bit of java is different from the bit of your OS.)
