Staff Assigned: Adam Robichaud (ASCOM.DLImaging.Camera) Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

In the meantime, can I downgrade to the previous driver?

Hi Adam,
One common denominator is that the OP and I both use the STF8300 with the SC-2. Although I do see the error happening without the STF8300 running, you might be able to persuade the SC-2 to show the error with the STF8300 taking data at the same time as the SC-2.

No. Can you please send link to 1.7.1.0. This version runs on my backup laptop with zero problems with SC-2. If running this version also produces the catastrophic failure on my imaging laptop then, it must be something to do with this laptop and not SC-2.

Here's an update. I actually have an OS backup of my main imaging computer which I reinstalled. (It's still a pain in the rear because it didn't have the latest version of Windows 10 version 20H2 build 19042.630 and needed to upgrade). The good news is that after the reinstall, I had driver 1.7.1.0 back and I've been testing this for a few hours and there's no catastrophic failure.

So I think it's a driver problem: 1.7.1.0 works well, while 1.9.1.0 is broken.

One other data point, I tried downgrading via using the SetupDLAPI.zip (1.3.0.0) that came with the SC-2. I had to uninstall the DL config utility first before the old setup would install. For whatever reason, this did *not* downgrade the driver from 1.9.1.0 to 1.7.1.0. My guess is that the uninstall did not uninstall the driver. Which driver would have been uninstalled? For the life of me I couldn't find it and so I just did the OS reinstall from backup.

Hi guys,
I just found that you've updated MaximDL and I thought I'd try it out to see if the Catastrophic failure is fixed. I installed all the files: MaximDL, DLConfig and ASCOM drivers to my backup machine from your site:






I installed it on my backup machine that had worked (driver 1.7.1.0) without any Catastrophic errors. Unfortunately, installing these updates, I get the Catastrophic failures . I restored my Windows partition from my backup and everything works again.
