Wix icon in Add/Remove programs - wix

Question

I am using Wix to create my installer.
According to the official documentation, if I want to change the icon in Add/Remove Programs, I need to add this:
<Icon Id="icon.ico" SourceFile="MySourceFiles\icon.ico"/>
<Property Id="ARPPRODUCTICON" Value="icon.ico" />
But it does not works, the icon is not changed and I also get the following warning:
C:\Users\rsheink\home\repos\tenlira\10Lira\TestWiXProject\Product.wxs(137,0):
warning LGHT1076: ICE36: Icon Bloat. Icon icon.ico is not used in the
Class, Shortcut, or ProgID table and also not used for ARPPRODUCTICON
property.
What am I missing please?
Thanks. Refael.

Answer 1

Request: Please comment if any of the below works for you - and also if you did something else (as well) to get things working.
Quick List First:
Is ARPPRODUCTICON spelled correctly?
Does the File.ico file have a hidden file extension? Example: icon.ico.bmp - 1.
Show file extensions in Windows Explorer
Open a cmd.exe in the folder and do a dir to check?
Icon file problems:
Is that a proper *.ico file? Try to save a normal *.bmp and rename the extension to *.ico. That should work for a rudimentary test icon.
Find a proper template *.ico file for testing (there should be plenty
in your Visual Studio installation folder).
UPDATE:
Please try to change this:
<Property Id="ARPPRODUCTION" Value="icon.ico" />
into this:
<Property Id="ARPPRODUCTICON" Value="icon.ico" />
I will leave the original answer below since the setup.exe issue might be relevant for others.
And one more thing: I was told that the dialog set <UIRef Id="WixUI_Mondo" /> is the better one in the available WiX templates. I have no hard facts apart from that recommendation though. I haven't used <UIRef Id="WixUI_InstallDir" /> - just if it can save you some time.
Old Answer:
This might just be a uppercase / lowercase issue. As in icon.ico instead of Icon.ico.
Correct:
<Icon Id="Icon.ico" SourceFile="MySourceFiles\Icon.ico"/>
<Property Id="ARPPRODUCTICON" Value="Icon.ico" />
Wrong:
<Icon Id="icon.ico" SourceFile="MySourceFiles\icon.ico"/>
<Property Id="ARPPRODUCTICON" Value="Icon.ico" />
During my testing I get the warning though, but the icon does work in Add/Remove Programs either way. Are you making a setup.exe bundle?
When you make a setup.exe bootstrapper bundle, you have to set the IconSourceFile attribute of the Bundle Element.
