So I had to setup a brand new WinXP SP3 and amongst other things, I installed Adobe Reader 11. But it wouldn’t start. It plain simply didn’t work.
I already had .NET framework 4 installed so that puzzled me. Googling showed up a bunch of irrelevant posts.
Then finally I figured… lets RTFM. (that’s normally the last thing you do when you’re an IT person).
And obviously, it’s there. Minimum requirements: IE 7. WinXP SP3 comes with IE6 by default.
So, download IE 8 (use a 3rd party site since WinXP is no longer supported by MS and as such they no longer offer IE7 nor 8 to download) and problem solved.
Enjoy.
