Post your Logtxt and we can have a look.

Simbrief (numeric) Pilot identifier set in User settings?

Yes.

You have a lot of rudder input going in (see the slip indicator below the FMAs), most likely unintentionally, but at Mach .80 even a small amount of input has a big impact. You should recalibrate your Yaw axis, and if there's still an issue, configure a dead zone at the centre of it.

The ATS mode screen you mean? Yes, depending on lateral mode and phase of flight, bank limit is adjusted automatically. 1/2 bank is also engaged automatically at higher altitudes. Changes the response of the autopilot so that it doesn’t chase the flight directors as aggressively.

Do you have multiple monitors? In a non-standard arrangement? A screenshot of the Windows display settings panel might help.

Turn the display and lamps’ brightness down! Your eyes are too sensitive at night.

Can you post some example screenshots showing PFD, MFD, and first legs page on the CDU, please?

That error is unrelated. But did you also check the X-Plane sound settings?

Make sure you have an active audio device selected in Windows and sound is enabled in X-Plane settings.

There is a password box missing. Change your display’s scaling and/or text rendering back to 100%/normal size.

Yes.

Once the F/O’s go-around procedure (not a checklist, technically) has been initiated it must be completed or cancelled via the top Challenger 650 menu, before advancing the F/O checklist automation (which is the function of the “check item” command). Any crash is a bug. But may be part of larger fragility in the automated F/O system. Thanks for passing on the log. Unfortunately it ends abruptly and doesn’t provide much useful debugging info.

Getting XP 12 and installing 1.7 only to that sim would be a good way of retaining 11/1.6 intact as a backup. Good idea.

What operating system? If Windows, you can do so via the Add and Remove Programs interface. You can always manually backup the prefs file and liveries from the current version. But the uninstallation should preserve them.

As it says, airport database is damaged, specifically the CL650's. Go to Output\caches\CL650 and delete airport.db.

LWR MENU on the CCP.

Suggest uninstalling the previous version manually.

Correct. HUD is now rendered by X-Plane. Feature. I think I can say with almost certainty that won’t/can’t happen (but I’m not the developer).

It is still relevant, yes. LR haven't made any significant changes that I know of.

Can you post a screenshot of the error, please? Also can you confirm you have V1.6 installed? If so, try manually uninstalling it before running the V1.7 installer.

There is still no way for the Challenger to get the detailed weather data it needs to properly simulate the weather radar, so no, still waiting on Laminar to provide this.
