RLS requires MS Word and Excel files for recording and printing test results.  However, you can use Open Office Writer and Calc as long as it is set by default to open .doc and .xls files. (.doc files will be opened on a workstation, .xls files on the server in a LAN configuration.)

Open Windows Explorer. Click on Tools, Folder Options, File Types. Click on the file types you want to open that file type. Choose the applicable program.

The file type for MS Word is .doc. The program in Open Office is Writer. The file type for MS Excel is .xls. The program is Open Office is Calc.
