Adobe Flash Player for IE; You can get it for free from Adobe's website.
Known incompatibilities:
Microsoft Office 2007 & 2010 64-bit; Uninstall it and install the 32-bit version with the same product key. Even Microsoft does not recommend the use of the 64-bit version of office with the exception of very specific and limitted applications.

Reason:Flash no longer required / MS Office no longer required
In Requirements I guess you also need to add MS Office since ACARS generates the locally saved report after each flight in .doc or is it recommended but not required ? (meaning it shall bypass the automatic .doc generation if no office exists without any errors popping up)
