Oracle client download for windows 7 32 bit install#
The solution was to uninstall the 64-bit client, install a 32-bit client in the 圆4 operating system, and then, however, if no web application (such as a console application or winform program) reports the same error, you need to set the non-web application project according to the following method, change the generated platform to x86 for normal operation. Is the generated program 32-bit, and then 32-bit calls the 64-bit client, so I changed the generate platform in the program attribute to 圆4 ,:Īs a result, the generated WebService program still reports the same exception during the call. Obviously, this prompt is incorrect, because we have installed a 64-bit client, so there is no situation where a 64-bit program calls a 32-bit client. This problem occurs when the 32-bit Oracle client component is installed in 64-Bit mode. If the application project is controlled or the winform project can connect to Oracle normally, but when the WEB Project opens the Oracle connection in the program, the system throws an exception:īadimageformatexception is thrown when you try to load the Oracle client library. Recently, a problem occurs when a colleague changes his computer and uses 圆4 windows 2008 as the operating system to connect to the Oracle database, therefore, a 64-bit Oracle client is installed. We usually use 32-bit machines for development and install 32-bit software, but our servers are generally 64-bit, so sometimes a vs debugging program needs to be installed in a 64-bit environment. In Asp.net, you do not need to use webdev for debugging. NET application successfully connects to the database server.ģ.

Note: If the 32-bit Oracle client has been installed, this test is not performed.2 installation sequence Set the debugging mode of the program to IIS instead of webserver.Ĥ because WebServer is a 32-bit program, if you want to use webserver for debugging, you can consider installing a 32-bit Oracle client (not tested ). Add the network service user to the administraotr group and restart the computer (important)ģ. Then install the SDK properly and configure database connection, such as tnsnames.

This article summarizes the related solutions. Some problems often occur during installation and development. Currently, Windows operating systems can be divided into two categories: 32-bit and 64-bit (64-bit also distinguishes x86_64-bit and itanium), and Oracle clients are also differentiated.
