install core from on computer to a replacment computer

want to install zbrush core on my replacement from a flamed old system but I cant get in the installer and other files to do this.

unless I miss understand this can be done from “mY license” but the system tell me that the info is invalid .

who to I contact to get help this outside of the support database?

If you can’t do it through My Licenses then you need to submit a ticket at Pixologic Support:

There’s no other way.

Thank’s for answering my question would like to get back working in this area
