During installation, the installation program checks the %SYBASE% environment variable for any existing Sybase directory that was created for another Sybase product. For example, this might be a directory created for Adaptive Server.
Sybase recommends that you install all products in the
same directory.
The following rules apply:
If the InstallShield installation program locates the Sybase directory, it installs DirectConnect subdirectories under this directory. However, before installation begins, you can specify a different location.
If InstallShield cannot locate such a directory, it creates one. The program creates only what it needs to install the product.
If InstallShield detects a conflict between new and existing files, you are prompted to choose whether to overwrite the file. At any point, you can cancel the installation.
