FRM-18107: Failed to create a DE context for the module

http://dbissues.blogspot.com/2016/02/frm-18107-failed-to-create-de-context.html

Resolved after deleting ORACLE_HOME from Environment Variables.

-----------------------------------------------------------------------------------------------------------------------------------

When starting Forms 10g Developer after starting OCJ4 Instance, I got the above error. 

I installed Oracle developer suite 10g after Oracle 10g server. (Windows platform)
Solution is to delete Oracle Home environment Variable. I just delete Oracle Home environment variable which points to, on my system, oracle 10g server which I installed at first. And everything works fine.
