    I was using one for the last few years that I really liked, but newer operating systems and other computer changes over the years have made it less and less compatible with anything I own, and I can't find an updated version. It looks like this:

    Any suggestions? Looking for one that can be downloaded, so that I can use it offline. Thanks!

    I just went to Google. Found this one a few days ago that works fine: http://freespace.virgin.net/matt.waite/resource/handy/pinouts/555/

    I'm using Win7 Pro, but the functioning of the program is independent of that. Why do you seem to want the program to execute on your PC? Why not just use LTSPICE (or similar) if you want a simulator on board?

    This is the same one I have been using the past month or so. I was just looking for one that I could download to use offline. I have no idea what LTSPICE is. I am fairly new to electronics. I liked the previous one I had because it allowed me to put in my desired times, and it would then give me the values.

    Here you go. Looks just like the old one, and it's working for me on Windows 8.

    EDIT: It is apparently the same one--same version and everything. Don't know why it's not working for you anymore--it's working fine for me.

    I get this error on the PC that I want to use it on when I try to launch the program. Not really sure what it means:

    Thanks, I've tried all that after you posted, still no luck. Think I am giving up on that one. I liked it too.

    Did you register the .ocx file after installing?

    If you installed it in c:\windows\system32\COMCTL32.OCX, then
    register it like this:

    regsvr32 c:\windows\system32\COMCTL32.OCX<enter>
