It should read "Patch 1 or later". You can upgrade any VSE 8.8 release to Patch 4 if -
- it's 32-bit and has Patch 1 or later, or
- it's 64-bit and has Patch 2 or later.
No, you're fine.
It's talking about the minimal steps to get from VSE 8.8 RTM (188.8.131.527) to Patch 4.
Patch 2 and 3 are fine to upgrade from.
Thanks. that makes it better that it was phrased wrong.
