Cannot load OCI

Post by robbak » Thu 01 Dec 2016 14:48

I have a Delphi 7 application on a 64bit Windows Server 2008 R2
using your trial version of dbexpora.dll
and setting the environment variable PATH and TNS_ADMIN to the directory where
Oracle 11.2 instant client is located, it loads without problem.
When I switch to the Oracle 12.1 instant client it says "SQL Server Error: Cannot load OCI: C:\instantclient_12_1\oci.dll".

Both clients are of the 32bit type...

I read your forums ... lient.html
and found the remarks about registry settings, but putting them in (Wow6432Node) doesnt fix it.

Any ideas?

The described problem is not reproduced, please make sure that you fulfilled all the items described in the blog and also if you downloaded exactly the 32 bit client
