ArcGIS customization can't find additional files

Hello,

I've made my first custom install program for ArcGIS step by step by this guide: http://edndoc.esri.com/arcobjects/9....1a3824474a.htm

Only problem I have is that my application cannot see my text files. For example, when I start application - error occurred: File C:\Program Files\ArcGIS\Desktop.10.0\Bin\dbA1.txt wasn't found.

Sure, because I have my files stored in installation folder, here: C:\Program Files\NewProgram\dbA1.txt

So how can I debug my files into ArcGIS BIN folder, or link my program to my install folder? I used to add text files into program My.Resources, but it can't be read them by StreamReader or change them by StreamWriter.

Any advice please? :)

thanks
