7.4 no launch

OK,I don't need any more crap. I searched all of the questions regarding no launch and can't find any exact answers. Here goes MBP 17" 10.4.11 2 gig ram digi 003 rack factory & micro 7.4.2 (99% sure since I can't launch? My install disks are 7.4) Yesterday I go to an outdoor interview session and plug in and click on the ball and get the double bounce and no launch. In case anyone wais concerned, I had to pul out the hand held and go into my Z-1. Anyway, I trashed prefs, did pre bind script, repaired permishes, tried to open previous sessions (many), downloaded 7.4.2cs3 AND 9 and upon install, it says I don't have 7.4. I'm thinking WTF but don't want to say it. I'm trying to have a good day but WTF? Is there any exact answer instead of a dead end thread? Sorry hard cores, trying to have fun but enough is enough!

I had the same issue with 7.1.1 on OSX 10.4.11. After I went to 7.3 cs8 all (so far) is well. I think the common denominator was the OSX security update that I auto loaded from Apple. Once I did that I had the bouncing ball. My temporary fix was to create another admin account and reinstall PTLE on that account. Well that worked but it was a cheesy fix. So I upgraded. Being that you are on 7.4 there may be the same issue or you may have installed the latest security update from Apple- I think it's dated Feb 2009 and that may have hosed you. I haven't installed that and will not until I get some postive feedback. Try the "define a new Admin account" fix. And if this works its the security update that hosed PT. I appreciate your frustration - I've been through similiar stuff. George

OK, I got PT to launch. Now my question is this. What is the highest level that 10.4.11 can install? It seems I have 7.3. I bought a micro that came with 7.3.1. When I tried to install 7.4.cs9 it says I need to go to OSX 10.5 Suggestions? Jeff

I didn't know what version I actually had since I couldn't open. FYI, here's what I did to get it working - from the tech FAQ's BTW. I created a new userand logged on with the second one. Logged right off. Deleted 2nd account and rebooted. Then it miraculously opened. So I downloaded 731cs8 and installed it. What's the next download? Jeff
