[WiX-users] AllowDowngrades="yes" warning LGHT1076 : ICE61

[Alain F. <af...@cm...>]

I've recently added the AllowDowngrades="yes" attribute to my MajorUpgrade element, which resulted in the following light warning:

warning LGHT1076 : ICE61: This product should remove only older versions of itself. No Maximum version was detected for the current
product. (WIX_UPGRADE_DETECTED)

In a similar post ( see http://sourceforge.net/p/wix/bugs/2405/ ), Rob explains that the warning is produced by the Windows
Installer / ICE team, and that they believe allowing downgrades or same version upgrades is a bad idea.

The reason I think we need to enable downgrades is if we push a new major upgrade, but find out there's some critical and
hard-to-fix flaw we missed, and then want to quickly and easily rollback to an older version.

So the warning is making me wonder if there's a flaw in my logic. Your thoughts?

Alain
