So I've been trying to get Wrye Bash to work because I'm trying to install All Natural (a weather mod with Real Lights). I've installed Wrye Python 04a and the one before (python25) but it has not work. Everytime I try the launcher it gives me this:

Error! Unable to start Wrye Bash.

Please ensure Wrye Bash is correctly installed.


invalid syntax (bosh.py, line 11389)

Please post in the official Wrye Bash thread.

That said, you have not installed Wrye Python and Wrye Bash correctly. My suggestion, uninstall completely through Add/Remove Programs (including all traces of Python), and reinstall. Also, suggest installing Oblivion outside of C:\Program Files...
