High DPI image displayed in the SD dialog not is deleted after setup

[cgentile]

Dears,

with InstallShield 2020 R2 if a high DPI image is displayed in the SD dialog, the image is not deleted after the installation. I also tried to restore the original image before the end.

Example:

DialogSetInfo(DLG_INFO_ALTIMAGE_HIDPI, SUPPORTDIR ^ "setup.png", 100);
SdDiskSpace2("", "", FALSE);
DialogSetInfo(DLG_INFO_ALTIMAGE, "", DLG_INFO_ALTIMAGE_REVERT_IMAGE);

Setup.png is presentIn the folder %TEMP%\....\

Is there a solution to delete %temp%\...\setup.png after installation is complete?

Regards,

Claudio
