It’s now available (to all VMware Partner) and some quotes from Vmware source :-

“New Version of VMware HealthAnalyzer Now Available
We are pleased to announce the availability of VMware HealthAnalyzer 3.0.1. HealthAnalyzer 3.0.1 resolves some known issues, and incorporates several previously released hot fixes for HealthAnalyzer version 3.0. In addition, this release is available in a full image of OVF virtual appliance; ThinApp packaged virtual application and a patch file. HealthAnalyzer users are free to choose any of the above options to update their HealthAnalyzer software.
Please refer to the HealthAnalyzer 3.0.1 release notes for a list of fixed issues and an instruction how to apply a patch to the existing VMware HealthAnalyzer 3.0. “

It’s good tool actually for you to do some health check on your customer environment but trust me, don’t just totally rely on this software. Some figure or items you have to manually double confirm for it. Although I never had any problem with the 3.0 Thinapp version before, I recommend you to go through the release notes.
