Sooner or later, XP Pro decides to die - and mine died on me last week. An effort at a repair reinstall failed, and it was necessary to wipe the slate clean, so to say, and reinstall everything from scratch.
I need to re-establish my basic GPO environment such that I can reinstall Sibelius 5 (last version). I already have ARIA and Sibelius 6, but have too much work in Sibelius 5 to simply let it go.
I've tried reinstalling GPO, but although the reinstall worked, I can not register it, therefore, it is useless to me right now.
I am in the midst of some critical professional work (a premiere coming up in weeks) and need to get myself up and running prestissimo.
This is probably not a thread for public discussion, but I am trying to contact whomever I can to resolve this.
At risk of staying on topic, let me offer this advice:
Try downloading the latest authorization applet from the NI web site and authorizing from that, rather than the one that came with GPO. It's still a pain, but a little less so.
(And don't try to update the authorization app from within the old version of that app. It may be possible, but I've never been able to get that to work. The best practice is to download the latest version from their web site and install it clean. In fact, I'd remove the old app completely before doing this. Not GPO, just that app that authorizes it. That's usually the source of the problem, in my humble experience.)
