I generated a VC++ program in my computer under Win 7 32bits linked to Oracle Instant Client OCCI 22.214.171.124 library. It works very well in my machine when selecting data from a database but, when I copy this executable together with oraocci11.dll (10.2.0.3 for VC10), oci.dll and tnsnames.ora to a client machine, which does not have VC++ but it has the VC10 distributable installed, it crashes with:
Faulting application consoracle.exe, version 0.0.0.0, faulting module unknown, version 0.0.0.0, fault address 0x003b003a.
in the 2nd line:
env = Environment::createEnvironment (Environment::DEFAULT);
conn = env->createConnection (user, passwd, db);
(env has invalid reference)
I spent many hours trying to solve this problem without success. The environment variables: path, ORACLE_HOME are appropiately configured.
What do you thing is happening?
