Audacity and Firefox usually show up red. PatchMyPC is reporting old, incorrect version numbers. For example, Patch shows my Audacity as 2.1.2, when in fact I have Audacity 3.0.2. Patch doesn't count these in the Apps To Install and it doesn't try to update them. It does give me extra work to check the versions of these apps in the apps themselves to make sure they're up to date. It only started doing this the last few months. It used to work fine.
This means you have older versions of Audacity and Firefox installed alongside the latest versions!
Make sure to remove the older versions correctly, and be careful with Firefox because it might remove the old and the latest together.
