add/remove programmer icon is not change

I had made a install.exe.
and now the install.exe's ico and uninstall.exe's ico is all right(it is saver.ico),but in add/remove programmer's the ico is windows defualt ico.why,how can change the ico in add/remove programm.thankyou very much.

try:
WriteRegStr HKEY_LOCAL_MACHINE "Software\Microsoft\Windows\CurrentVersion\Uninstall\${SAVERNAME}" "DisplayIcon" "${ASSETSDIR}\saver.ico,0"

but the add/remove programs app has a mind of its own when it comes to icon and size 🙁

ok,i see.
WriteRegStr HKEY_LOCAL_MACHINE "Software\Microsoft\Windows\CurrentVersion\Uninstall\${SAVERNAME}" "DisplayIcon" "${ASSETSDIR}\Unistall.exe"
not saver.ico
