hi dear, i have question about instalation of tizen studio.

so honestly i have to try instal tizen studio and getting success at all in many computer or laptop of my friends.

but i got a bit problem now, so i have to install Tizen Studio 1.2, and at the part where i must install Samsung Certificate Extension at Extension SDK or Configuration, i still can’t see Samsung Certificate Extension. i try to change the package repository url but still at extension sdk i can’t see Samsung Certificate Extension.

any idea about that?  thankyou so much..
