Subject How to get FB 3.0 x64 work as embeded version?

Dear Sir/Madam,

After FB 3.0 released, I am trying to immigrate my DB application to this new version.

My DB app is running with embeded version before, so now I am still trying to get it work under embeded mode.

I tried FB 3.0 x32, it works as embedded version well after I created a new user SYSDBA (as in FB 2.5).

But for x64 package, I got error like this:

Error message:
[FireDAC][Phys][FB]-314. Cannot load vendor library [fbclient.dll or fbembed.dll]. fbclient.dll has unsupported architecture [x64]. Required [x86].
The specified module could not be found.
Hint: check it is in the PATH or application EXE directories, and has x86 bitness.

What I have done (same as x32 package):
1. Unzip FB3.0 x64 zip file to a folder.
2. Run isql to create a new user SYSDBA with password masterkey.
3. Copy my DB application to this folder.
4. Run this application and got error.

OS: Windows 7 x64 Ultimate English
FB: No firebird server was installed as service.
DB: FDB file is upgraded to new format v12.0.

Best regards,
