Occasional ContributorQuartus did not start
Hi,
Since the switch to European Summer Time we cannot start Quartus Prime 2025 in Windows 11.
Error Message:
The application could not be started correctly (0xc0000142)
What could be the reason for that?

Noted, I am in the progress to duplicating this case. stay tune.
billmaxAnother observation is that manually running qreg.exe also fails in a similar manner, and may be easier to trace than full quartus.exe. I've attached the list of the modules loaded at the point in the qreg.exe process it calls the windows error handler C:\WINDOWS\system32\WerFault.exe

Can you paste the whole error message here?

Have you installed the patch:

Or just got to 26.1 that came out yesterday.

The Installer for 26.1 generates same error.

Hi KennyT,
please take a look at the attached jpg in my first post. That's the whole message.

Hello, we are experiencing exactly same error on multiple machines with Quartus Prime Pro 25.1.1.
It's started last week. Please help.

Hi strell,
we installed the patch but the same behavior unfortunately.
- syoma
Same too :-(
- billmax
Same with QuartusPrimePro 24.1, started late last week. Windows Application event log ID 1000, with no useful information. Pop-up Application error 0x142 as noted in the original post.
I've got a full PML log from SysInternals ProcessMonitor of the failed start if it would help.
{edited to correct for ProcessMonitor)
{amended to add: multiple machines under Win11, similar failure without popup on another Win10 machine)

Can it be somehow connected to german localization of Windows? Seen from screenshot - I have the error message also in german language.
- KennyT_altera
Please give us some time to investigate.
Billmax, Syoma, did your computers also switch to European Summer Time? I want to check if this issue is related to the computer clock settings.- syoma
Yes, they did. But this happened on Sunday 29.03.26, and I'm quite sure, the software was still working for a few days after that.

We are eastern U.S. on EDT for a few weeks.
We originally suspected (and haven't ruled out) an issue with corporate cyber security program(s). But we haven't figured out what might have changed to break working installations. In theory it's all still white-listed.

We tried to swith to EU time zone, German languange on windows 11, but we do not see the problem. Attached the screenshot later, is there other suggestion that we can try to duplicate the issue?
We will try manually running qreg.exe also.
- billmax
We don't know what happened to break it, and no updates we're aware of were made to any systems or protections during the interval it went from working to not.
Other than the developers taking a look at the list of modules loaded by qreg and seeing why it would exit with error 0x142 at that point, I'm not sure what to suggest.
