there shoud either be a photoshop version number/CS/CS2/CS3 folder inside, depending on what versions you had installed. now copy your brush patterns/ plug ins to plug in folder inside the photoshop folder of the version you still have installed.
Is it possible to add more RAM to a laptop? I like playing a couple of computer games, and sometimes my computer lags or displays the 'low on virtual memory' message. So, I thought the easiest solution was just to add more RAM, but then it's a laptop, so my dad says you can't add more RAM. I'm so confused! 
virtual memory isnt RAM, it's hard drive space. windows will grab a chunk of your hard drive space to compensate for low physical memory (RAM) and use that. programs wouldnt really know the difference and they will start, but you will know if it's using virtual memory because it runs slower since it has to access the disk every time you do something. now, if a program that's using virtual memory crashes, windows will still think that the virtual memory is still being used, so when you open another program, even the same one that crashed, it will give you the low on virtual memory message. this can also happen to poorly designed programs, beta releases for example. if this happens, press ctrl+alt+del to get into the task manager, go to the processes tab and terminate the program from there. then restart.
another thing to do that may alleviate the problem is to allow windows to automatically manage the virtual memory.
if you did that and still having problems, it's time to upgrade your RAM. for notebooks, look for SO-DIMM RAM, normal desktopp RAM wouldnt work because, well, it wouldnt fit.
