I'm not sure this is possible. But why would you like to do that in the first place?!? End-users should be allowed to close the installer if they changed their mind.

yes,you are right.

but sometimes, when i click the 「×」 button while it's installing，the link of uninstallation will disappear.

Well, this is quite normal, as the Uninstallation can be created only when ALL items have been installed (so IA would know how to proceed with Uninstalling those components in the reverse order). So if you click close BEFORE the end, the Uninstall doesn't get a chance to be created (or just the link to it).

Hi,
Please try the following. This is working on a custom dialog.

#define DIALOG_NAME_1 "ShowMsg"
HWND hWindow;
LONG lstyle;

hWindow = CmdGetHwndDlg(DIALOG_NAME_1);
lstyle = GetWindowLong(hWindow,GWL_STYLE);
lstyle &= ~0x00080000L;
SetWindowLong(hWindow ,GWL_STYLE,lstyle);
