    private void printdocument1_printpage(object sender, system.drawing.printing.printpageeventargs e)     {         e.graphics.drawstring("hello world", new font("times new roman", 16, fontstyle.bold), brushes.black, 10, 10);     }      private void button1_click(object sender, eventargs e)     {         string str = "";         (int = 0; < printersettings.installedprinters.count; i++)         {             str += printersettings.installedprinters[i] + "\n";         }         messagebox.show(str);         try         {             printpreviewdialog1.document = printdocument1;             printersettings prnset = new printersettings();             if (printersettings.installedprinters.count > 0)             {                 pagesettings ps = new pagesettings(prnset);                 ps.margins.left = 10; ps.margins.right = 20; ps.margins.top = 10; ps.margins.bottom = 20;                 printpreviewdialog1.showdialog();             }                     }         catch (exception ex) { messagebox.show(ex.tostring()); }                 }      private void button2_click(object sender, eventargs e)     {         printdialog1.document = printdocument1;         printdialog1.showdialog();     } 

when run vs works, when run release folder - exception:

system.componentmodel.win32exception (0x80004005): server rpc unavailable @ system.drawing.printing.printersettings.get_installedprinters() @ printstudy.form1.button1_click(object sender, eventargs e) in c:\printstudy\form1.cs:line 37 @ system.windows.forms.control.onclick(eventargs e) @ system.windows.forms.button.onclick(eventargs e) @ system.windows.forms.button.onmouseup(mouseeventargs mevent) @ system.windows.forms.control.wmmouseup(message& m, mousebuttons button, int32 clicks) @ system.windows.forms.control.wndproc(message& m) @ system.windows.forms.buttonbase.wndproc(message& m) @ system.windows.forms.button.wndproc(message& m) @ system.windows.forms.control.controlnativewindow.onmessage(message& m) @ system.windows.forms.control.controlnativewindow.wndproc(message& m) @ system.windows.forms.nativewindow.callback(intptr hwnd, int32 msg, intptr wparam, intptr lparam)

i tried restart printer spooling process no result. (user has admin privileges).

p.s. setup debug->exceptions check in thrown in vs vs shows me exceptions during debugging, vs started program without problems. why problems appear when run release/debug folder? , how solve it?
