SdShowDlgEdit3 displays "@10550,10551;1;0;;0 ..."

Hi, all.
May be someone can help me.
I work with InstallShield Developer 8.0 Basic MSI project.
Operating System - Windows 2000 with SP3.
I use the SdShowDlgEdit3 function to display the standard dialog.
But it is not work good.
It displays “@10550,10551;1;0;;0,128,128” text in the up-left corner of the dialog.
I understand that this “garbage” displayed instead of bitmap and for some unknown reasons this bitmap was not found.
I used DialogSetInfo function to set my own bitmap. But it doesn’t help: bitmap was not set, and garbage was not disappeared.
May be I do something wrong?
This is my code:

…
SdInit();
iRes = DialogSetInfo(DLG_INFO_ALTIMAGE, "c:\\BitmapId_103.bmp", TRUE);
SdShowDlgEdit3 ("Test title”, "Enter properties", "IP", "User name", "Password", svIP, svUserName, svUserPwd);
…

Thanks in advance
