## Advisories

### Advisory 1

Alchemy's Compatibility Package Editor should only be used to update applications, files, and registry redirections on the same architecture on which the original Compatibility Package was created. For example, if the Compatibility Package was created on an x86 machine, then the Compatibility Package Editor must be run on an x86 machine to update the Compatibility Package.
