Follow these guidelines if you are installing SDK on the same machine with other Sybase products:
In general, Sybase recommends that you place the new installation of SDK in separate directories from other Sybase products, such as Replication Server, OpenSwitch™, Enterprise Connect™ Data Access, and Sybase® IQ, unless Sybase Technical Support has specifically recommended installation in the same directory to address an issue.
Installing SDK 15.7 on the same machine as Adaptive Server 15.0.x could cause Adaptive Server to fail to start. To configure this configuration, either upgrade Adaptive Server to 15.7, or follow the directions in the Software Developers Kit and Open Server Installation Guide for Microsoft Windows.
Sybase recommends that you do not mix versions of SDK and Open Server in the same directory. For example, do not install SDK 15.7 in a directory containing Open Server 15.5—in this case, upgrade both SDK and Open Server to 15.7.
