The problem appears to be related to SnagIt not being designed for large desktops (by large I mean >50 megapixels. My desktop is 132mp (16 4K monitors).
The symptoms are that SnagIt will start with system startup, but when you hit the shortcut key (or capture manually), it crashes without doing any capture. It appears that it is choking when it tries to process the size of the desktop).
I can say from memory that in PREVIOUS versions, the limit was very low - around 8 2K monitors = about 30 megapixels. But that was a few years ago in v 10 or v11. I have re-tested it using the lastest version on my 132mp system and get the same results.
This has been reported to support at least a dozen times. I absolutely LOVED snagit back when it used to work correctly on large systems (pre v9), and I even ran an old version for a few years to cope with the fact that newer versions no longer worked. But I lost the old install kit and all recent versions fail with the same symptoms.
DEVELOPERS: What better opportunity to hit your boss up for a REAL test system! It's obvious you guys have never tested this product on a serious multi-monitor system (100mp+). Curiously, it worked fine pre-v9, although at that time I was only running a "girly man" 30mp system. Hit the boss up, get yourselves a real test system, and fix the product so I can buy it again, please. I miss it SOOO much!!!
Thanks,
Erik
p.s. I'm running a 128GB system. The issue is not lack of system resources. The problem appears to be that SnagIt was never designed/tested on very large desktops and there must be an integer overflow or some other issue causing it to choke when you run it on a serious multi-monitor system.

To answer your question, I have 3 65" monitors, 4 55" monitors, and the other 9 are "antique" 30" and 32" 4K monitors I bought before the big ones became affordable.
Eventually we'll use AR for everything and won't need any monitors, but AR technology still has a long way to go. Until then, we still need a lot of monitors to set up a proper computer. I pity those who are so narrow-minded as to think they would have no use for something they've never tried, but people in general have never made much sense to me... ;)

2 NVS810's runs the whole bunch, all connected via DisplayPort.
Quite a lot of software doensn't know what to do with a big desktop - it's definitely not just SnagIt.

This thread is the first I've ever heard of anyone that has maybe three monitors connected.

Still the setup sounds legendary and I'd love to see a picture.
There's a guy at work with I think 6 monitors, it's be great to show him something he can aspire to.

Each monitor is 1920 x 1200 and side by side so windows creates a 5760 x 1200 desktop, no holes.
If monitor two were 1920 x 1080, the virtual desktop would still be 5760 x 1200, but there would be a hole, bottom middle (1920 x 120). So it's hard to imagine your virtual screen without many, many areas of undefined space.
Then near the bottom, click "advanced display settings", all three are identical & I never have a problem.

I can program in a fixed 5760 x 1200 pixel space, can stretch excel and create 5600 x 1120 charts, etc. No wholes. BTW, Tech Smith can't fix "holes".

That said, here's the current configuration. Note that several monitors have been configured in reduced resolution - this has nothing to do with the SnagIt problem, and the symptoms would be identical if all of them were operating in 4K resolution. I know this from actual testing.

and large hole bottom center. Here's a Snagit test:
snag top/left of 12 to bot/right of 13. Or top/left 5 to bot/right 6. (no holes). What happens?

Connect 12, 3, 16, 15, 13, 7, 8, & 14 into a 4 x 2 configuration. Does it work?
If your unwilling to test it, I don't think any of us can be any further assistance.

I have the impression you and the others who are responding here are users, and are NOT Techsmith product engineers. If that is correct, I appreciate your well-meaning desire to help, but you can't help me. The only people who can help are the Techsmith engineers who probably don't even realize their product has been broken for several years now, because they don't have a serious multi-monitor system to test it on.
If you ARE a Techsmith engineer, please say so. I've already explained more than once why the tests you are suggesting are completely unnecessary, but if you are from TechSmith engineering I suppose I'll go through the motions to appease you if it will persuade you to look into fixing SnagIt.
Thanks,
Erik

I for one don't want to pay for any of your hardware abuses, OK?

I also wonder if monitor 1 on the right poses a problem as they'd need negative numbers going back that far.
Just for kicks you could try dragging monitor 1 to about the middle of the grouping and see if Snagit still crashes? You might also try to create a grouping that's more square so the total number of pixels across is under 32,768 (for testing purposes of course)

Have you tried installing SnagIt 8 to see if it works with this newer setup?
The reason I ask is SnagIt 8 runs on my windows 10 computer. Same applies to versions 5,6 and 7.
I've had to install some older versions using an original key. My newer keys just don't work. However, new keys are supposed activate all previous versions.
You could download an older version here. Try your current key to activate. https://www.techsmith.com/download/oldversions
If that doesn’t work, perhaps TechSmith will provide you a key? Its might be worth a try?
I realize you aren’t seeking member support.
Based on what you posted. Free Tech Support hasn't gotten you anywhere.
Regards,Joe
