1) Change target host version from v2.01 to v2.02. It is specified in makefile of your .RTU in HostVersion field. Just change it from 22.214.171.124 to 126.96.36.199. 2) Path to description is specified into Description field of your makefile: %RTFolder%\Help\Updates\ItalianLocalization.rth Just create text file with the same name located in RivaTuner's .\Help\Updates subfolder and rebuild .RTU and it will be automatically integrated into it as description. For example, there should be something like: Italian language pack v188.8.131.52.0 Contents: - Localized user interface - Localized external help files Also, please change CreatorICQ field from N/A to blank field into makefile just like you did it into localization description. I could easily do the changes myself, but I suppose that our dialog can be a good tutor for the rest localization pack creators.
