ConEmu environment variables

Question

Situation:

1. script1 (written in python) run from ConEmu and set SQLPATH (global, with setx /M command)

2. than run script2 (written in python) from ConEmu, which runs sqlplus (uses SQLPATH environment variable)

script2 can get SQLPATH only if I run this.

ConEmuC /export PATH

which tell

ConEmuC: can't export environment to PID=4124, check < Inject ConEmuHk >

when I try to inject ConEmuHk.dll python process ends unexpectedly.

How can I make script2 use SQLPATH in this situation?
