Harmans SDK 33 with flash builder 4.7 JAVA Error

I am trying to install Harmans SDK 33 with flash builder 4.7. I believe I have installed the SDK correctly. When I run my app using the simulator, I get the Harmans logo and everything seems to be functioning as expected. However, if I try to build an export release I get an JAVA error. I tried to copy my java contents over into flash builder but flash builder wont start up after the copy is completed.

All contents from
C:\Program Files\Java\jre1.8.0_251\
Into
C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\jre\

I also un commented these two lines out in the adt.cfg
DefaultArch=armv8
OverrideArch=armv8

Error occurred while packaging the application:

Any Suggestions ?
