I have developed an application that uses the RichTextBox to do syntax highlight. I am developing on Window$ 200 $erver Editition with VB of course. When i run the project from vb, everything is OK. The same when I make an exe in my computer. When I try to make an installation using windows installer (from InterDev), a strange thing happens. My RichEditBox is not the same as the one I see when I run the project from VB or .exe ! Not even in my computer!!!! For instance while in vb run or exe, my RTB supports background highligting, the installed copy of the program does not! I have searched the net and I suppose it has something to do with RichTextBox versions (riched32.dll and riched20.dll) but that is as far as I can get... Any suggestions?
