I installed Oracle 11g on my laptop Windows 7 64bits. I created my first workspace and when I tried to start the designer I had the error: Application couldn't start correctly 0xc0000018.
I checked on the internet and discovered that this error existed since 2010. Is there a solution for OWB on Windows 64?
You will need the OWB standalone client for windows 64 bit. Even though you may have 64 bit database, the OWB client bundled there is not 64 bit.
OWB 184.108.40.206 Standalone client for Windows 64 bit (13365470)
Install 220.127.116.11 database, and use the 18.104.22.168 OWB client for it. There was an announcement on forum on the OWB 22.214.171.124 cumulative patch which is also advised, not sure if there are more, but it's worth checking.
