PowerBuilder typically writes to multiple files in the Program Files directory, including pb.ini, PB110_sysam.properties, and code examples, tutorial, and demo database files. If an application is run without administrative privileges, Vista restricts it from writing to the HKEY_LOCAL_MACHINE subtree in the registry, the Program Files directory, and the Windows directory. Instead, changes are written to a writable area in the registry and to the user’s local directory. This is referred to as virtualization.
For example, if you start PowerBuilder without administrative privileges, the pb.ini file is written to Program Files\Sybase\PowerBuilder 11.0\pb.ini in the C:\Users\<your_name>\AppData\VirtualStore directory.
To avoid the issues that would result from this behavior, on Vista, you must start PowerBuilder 11.1 with administrative privileges by right-clicking pb110.exe in the Start menu or Explorer and selecting Run as administrator from its pop-up menu.
