Problem with Loadrunner 12.53 (Oracle database connection)

Hi,

i have a problem with my Vugen. I want to record a script for testing a oracle database.

If i record the script with Toad everything is fine but if i want to replay the script i get the following error:

vuser_init.c(13): lrd.c/fjInitDB: None of the library combinations specified in section [ORACLE_WINNT] in the "lrd.ini" file could be loaded. Initializing for ORACLE failed
vuser_init.c(13): lrd_initialize_db: ERROR, return-code=LRDE2015.

I dont know what i have to do to fix this problem. I think the Vugen cant locate the binaries of Oracle client but the Path variable is set to the binaries so what do i have to do to fix this ?

Loadrunner version : 12.53

Oracle version 11

Thanks for any replies.
