The i18nsearch.dll file is from the original OpenOffice from Sun Microsystems, Inc. Sun created an office suite called StarOffice and decided to release it as open source code. When they released it, they renamed the suite to OpenOffice.org and offered it free to all users.
Because it is free and useful, development has continued on the suite and new versions are released regularly. This file was a component of early versions of OpenOffice, but it does not show up in the latest version of the software.
Open source files like this can sometimes be reused in other programs. If you have never run OpenOffice on your machine, you may still have a program that uses this file. And if you are running OpenOffice, you may just need to update your version. If you get an error with this file, it usually means there is a problem in your registry.
The registry keeps track of all the parts of all installed programs on your system, and can sometimes get out of date. Clean your registry with ZookaWare PC Cleaner to find and fix all registry errors and keep you system running smoothly.
