Hi Larry,
Welcome back, and thank you for your support
I assume you have downloaded this file:
PI-win-x86-01.02.05.417-nsi-20080821-c.exe
in case you have a 32-bit Windows version, or:
PI-win-x86_64-01.02.05.417-nsi-20080821-c.exe
if you're running a 64-bit version.
Anyway what you've downloaded is a common Windows installation file -just run it to perform the installation. The time-limited betas were just self-extracting compressed archives, but now we have true installation packages and all
Before installing the new version, I recommend you to erase the old beta version, if you still have it, to avoid potential problems. Read the instructions email _completely_, and just follow the instructions.
Tell me if it works well.
Cheers,
Juan
