Latest questions about "hmex assistant"

Call me regarding a multi user license for our Fire Department OCFA. 714-573-6253 We have a year 1999 version, and the Version 6.2 year 2010

We recently purchased 4 copies of Hmex 6. But our IT group will not install on more than 4 PCs

Are there updates for the HMEx Assistant? And if so, what do the updates consist of? Any help would be greatly appreciated, thank you.
