What does ICE73 check?

ICE73 verifies that your package does not reuse package codes, upgrade codes, or product codes of the Windows Installer SDK samples. Packages should never reuse the package, upgrade, or product codes of another product.

When does ICE73 show up?

ICE73 outputs a warning if your product's package reuses a package or product code of a Windows Installer SDK sample.

How can I fix ICE73?

To fix ICE73 errors, generate a new unique GUID for your package's product, package and upgrade codes.
