I started the IDE download tonight. It's now been running over four hours and progress bar indicates it's only half done. Is this normal?
Nope, I just downloaded it in under 30 seconds on my cellphone
Grrr! I misspoke. What I meant was the install has taken 4+ hours to this halfway point.
That is probably down to some other software you have installed on your computer eg a very aggressive anti virus or some such.
Also when was the last time you did an extensive CLEAN UP ?
