Setup routines... in OraClient11g... could not be loaded: System error 193
SebulbaApr 11 2011 — edited Feb 26 2013I am working on a 64-bit Windows 7 platform. I initially installed the 64-bit version of the Oracle client 11g R2 only to later discover that the 32-bit version had to be used. By error I installed the 32-bit version in a wrong directory and wanted to wipe both installations out and start from scratch.
I figure that something is not configured properly in the registry because when I run the ODBC Data Source Administrator and try to add Oracle in OraClient11g_home1 as a data source the following errror message appers:
The setup routines for the Oracle in OraClient11g_home1 ODBC driver could not be loaded due to system error code 193: .
Moreover, if I deinstall the client, edit the registry to remove all keys containing the word oracle, reboot the machine, re-install the cient, the ODBC administrator does not show that the client is installed. I have no idea what to do next.
