Guys! Seems I found the decision of this problem. Beside I personally appeared such error, when in list of the installed programs stood the Office. When I check out Office, error was not. Here is my decision: 1. Make SFX-archive (only unpacking; for example in C:\OFFICE) 2. The first program must must be the batch-file with such text: @echo off start msoffice.exe exit (This script starting unpackagin' archive (msoffice.exe) with Office installation files to C:\Office in silent mode. Use start only, not start /wait!) 3. The last program must must be the batch-file with such text: @echo off start C:\office\setup.exe /settings setup.ini exit (This script starting Office installation. Use start only, not start /wait!) If you will do this, error with rb_config.js will not appears. Why? I don't know. As for me, with my WPI (6) it works. Office 2003, full, Ru. PS I have tested this method on different computers and everywhere I tested it works!
