Xplane 12 is CTD upon latest Xplane update (3/31/26)

[Mbolton1]

Xplane update deployed today - 3/31/26 causes immediate CTD.

Re-installing, and plugin probes turned up nothing.

ALL other planes in my X-Plane installation load fine.

Just thought you should know.

Thanks. We know. A beta to fix will be out soon. (See numerous other threads.)

Thanks for the info, @Pils and @Cameron.

Can you estimate how long this will take? Days/weeks/months?

I’m wondering whether it’s worth spending $60 on Steam to install the previous version (12.4.0) of X-Plane and transfer all my settings. Unfortunately, for once, I didn’t back up my X-Plane folder before installing the last minor update

It's not worth doing. Laminar can instruct you on how to downgrade if you contact them. We hope to have an update out on our end within the next week or two.

Hi,

2 addons crash xp12.4.1 the hotstart and the tbm 900.
It's impossible to downgrade XP 12. I have asked to Laminar, the answer is : "We do not keep previous versions but do advise you to make a back up before updating". Comical...
For me I paid 125 € for the challenger.
So when i see that  you hope an upgrade within the next week or two....
I'm not going to say what I think about it

We can't INSTANTLY come out with an update when a new version of X-Plane comes out.  As much as we want to, it's unreasonable to expect that from anyone.  

In the X-Plane world, many developers always recommend to keep 2 installations of X-Plane.  A stable version and a beta.  

Regarding the Challenger update...we're currently on beta 3 within 1 week.  That beta is in the hands of our testers.  3 beta's in 1 week is quite fast.  

There are only 2 of us on the Hot Start team.  We can't work on two products at the same time, so while the Challenger is getting updated, we're going to ask people to continue to be patient for the TBM.  

If you expect an update in the next week or two, all I can tell you is the update will be out when it's done.  We want it out as much as you do.  But it doesn't make sense to put out an update that isn't ready.  

Whatever you think about the situation is entirely your opinion.  It will have no influence on how fast the updates get done.

This is absolutely NOT true. It's just their technical support team using canned responses to get rid of you.

If you run the installer with --install_name="X-Plane 12.4.0-r2-9b69b91a" command line option then it will downgrade when you select "Update X-Plane."
