invalid character and XML Log

[iryshia]

I think I know what is the problem, but I don't find a solution. In the builder log, Visual Build don´t know to convert the "invalid character" to a "valid character". VB does the same conversion well in other PCs. Installshield 10.5 produces the "invalid character". This problem happens with versions 6.1 and 5.7 of VB, and with the "Windows XP Home".

This is a fragment of the build log with "invalid characters":

D:\DailyBuild\20060517\SurferMatrix\Install\Instal adores_v10.5\SurferMatrix\Script Files\Setup.rul(791) : warning W7503: '_DeleteNTService' : function defined but never called
