Will I lose CS4 if I upgrade to OS 10.7 Lion?

I use CS4 in conjunction with LR3.

    I have a MBP with 10.5.8 and recently downloaded Lion. I was disappointed when I could no longer open PS (CS4). Illustrator is fine but I need PS for work. I tried uninstalling and reinstalling PS a couple times, and installed JAVA, like I was told. Eventually I just had to uninstall Lion, even though I liked many of its features. From what I am reading it seems that I will have to wait to reinstall Lion once I can upgrade to CS5. I am just wondering why it would work on a new MBP,with Lion preinstalled, and not on a download. And why Adobe would not update CS4 to work on Lion? It's a money thing I'm sure.

    Ugh! I was hoping it would go so smoothly.:(

    In our testing, Photoshop CS4 worked on Lion.

    Some specific system configutations seem to have bugs in the video card drivers, and some third party plugins need to be updated - but that's it.

    If Photoshop CS4 wasn't even launching on your system, then something else was wrong on your system.

    How can I find out why PS wouldn't open?  I kept getting an error

    saying it is not compatible with Power PC or something like that.

    Illustrator worked fine, or at least opened. Are actions that I

    downloaded and installed in PS considered third party apps? I even

    tried uninstalling PS and reinstalling and it still wouldn't work.

    What do you suggest? I would love to install Lion and have PS work

    with it so I don't have to upgrade to CS5. Help!

    I have Lion installed on a MBP (2.66 Ghz i7 with 8GB RAM) installed as an update on top of a working system. My copy of Photoshop CS4 fully updated with all the java updates etc. Things worked fine until I tried to move the order of a layer, moving a layer below another. Every time I did this PS crashed. Every time. I have to admit that It was a fast session and I haven't done extensive testing (my main machine has not been updated - and won't now) but this crashed it every time I did it.

    I didn't do any updates to my CS4 after installing on my 2.2 Ghz Intel Core i7 MBP. Just tried to move the layers around using Apple key + [ and ] and didn't have any issues. While I was at it, also tested whether I could change the opacity of a layer and apply some blending options like drop shadow without problems.

    I just tried it with the key commands and it indeed workswith them. Dragging layers does not though. Opacity and Fx and every other thing I've done seems to work in the layer pallette except for draging layers around.

    You will not lose CS4 by upgrading to Lion. Since it is coming out this month, you may want to wait and watch the forums for a month incase any problems arrise.

    Often .dot upgrades are not very risky but actually 10.6.5 to 10.6.7 have a tech ical problem with Adobe apps and keyboard modifiers that some people experience. We are hoping that 10.7 Lion will fix this as enough posts have been on these forums adn others about this.

    So if you cannot risk any downtime, I would wait a month or 2. If you like to be on the cutting edge and are wiling to deal with the risk of a possible glitch or 2 then upgrade now.

    Thanks, Mike, great suggestion(s).  I appreciate your taking the time to address this.

    I called Adobe support and the rep said he wasn't sure about whether CS4 was compatible.

    I've been sticking with CS4 because I have numerous 3rd party apps (OnOne, etc) that won't

    work with CS5 and hate to lose them or have to re-invest.

    I'll wait, per your advice, and see what transpires.

    This forum is terrific.

    Best regards,

    Frank DiMarco

    No problem. Forgot to mention one important issue earlier. If you are on a Mac with an older Power PC chip then don't upgrade to lion because Rosetta is going away. Read more here
