Before upgrading, we recommend making backup files for each of your PHRs, and saving them someplace.
Then on the new computer, you can re-install HealthFrame, and restore from those backups.
From your description, its unclear exactly what you've done. If you simply updated your copy of Windows in-place, then HealthFrame (and any other applications you already had installed) should be on the new computer already, along with your existing data.
Since you are asking, I assume you didn't do that.
Please clarify how you did your upgrade, and whether or not you saved HealthFrame backup files first.
