I have personally tried the following 64-bit Windows LibreOffice versions, all of which hang during application start-up:
Other users (see thread links below) have reported the same problem with these 64-bit versions:
Note: I have reset my profile and disabled OpenGL without any luck. 32-bit Windows versions appear to be unaffected and just work.
My machine is a Dell Latitude E6520 with a 4-core (8 hyper-thread) Intel Core i7-2760QM processor, 8GB RAM running Windows 10 Professional 64-bit (version 1511 - NOT the Windows 10 "Anniversary Edition"). In case it's relevant, this machine has both Intel HD Graphics 3000 integrated graphics and an NVidia NVS4200M graphics card. I've tried running LibreOffice with both cards and both result in the application hanging.
Refer to these threads for more information:

https://ask.libreoffice.org/en/question/76494/64-bit-libreoffice-515-520-freezehang-while-opening-files/ (a thread started by someone else with the same problem).
(I have a Microsoft Surface Pro 3 that is successfully running 64-bit LibreOffice 188.8.131.52, so this is clearly not a problem affecting every PC.)
Let me know if there is any further information that you require.
Steps to Reproduce:
1.Run any LibreOffice application, either standalone or by clicking on a LibreOffice document.
LibreOffice logo appears, application hangs. The soffice.exe program then goes into an infinite loop, consuming all available CPU on a single thread.
Application should start up normally.
User Profile Reset: Yes.
Also tried clean reinstall and also tried disabling OpenGL - no use.
32-bit releases (the 184.108.40.206 release, at any rate) are unaffected by this problem.

Did you check, if you have this installed: Intel OpenCL SDK? LibreOffice Calc is able to use OpenCL, so I guess removing that SDK worked for those people in the thread because some conflict was removed.
As requested, text from the Writer Help/About LibreOffice dialog:

LibreOffice was based on OpenOffice.org.
I do have "Intel SDK for OpenCL - CPU Only Runtime Package", version 220.127.116.11149 installed.
For the record, the problem affects all of the LibreOffice applications, not just Calc. I would prefer not to uninstall this software, because I do not have an installer for it available, so I cannot reinstall it should it prove to be required.
It might also worth mentioning that the Intel OpenCL SDK is NOT installed on my Microsoft Surface Pro 3, which runs the 64-bit version of LibreOffice OK.

You can get the installer here: https://software.intel.com/en-us/articles/opencl-drivers
If you do not do
- scientific computation
- physics simulations (hard/soft/rigid body, cloth, fluid, smoke etc.)
- some other number-crunching thing that requires OpenCL
I don't think you will miss that Intel SDK for OpenCL.

Unfortunately, simulations are what I do for a living. :-(
Also, the particular version of the SDK that I have on my machine doesn't appear to be listed on that site (I had already checked it out). My concern is that it's a requirement for one of my simulation tools (and I haven't got time to uninstall/reinstall each one to find out if it is the reason LibreOffice doesn't work.
Either way, LibreOffice should not hang just because I have an SDK installed - and it certainly shouldn't in applications that do not use OpenCL.
Ok, let's throw it to NEW based on the Ask.LibO thing and the strong suspicion that it is because of the SFK.
Can you check if there's an <user profile>/cache/opencl_devices.log files, and attach it if exists? There's a chance it won't, but you never know...
If we can get the OpenCL driver version, it should be worthy of blacklisting.
Created attachment 130184 [details]
opencl_devices.log file, as requested.
By default, applications run using the Intel HD 3000 integrated graphics. However, I also tried using the NVIDIA 4200M card with the 64-bit LibreOffice. The hang occurred with both cards.

This file was also present, so I'm attaching it just in case.
Thanks for your assistance with this. Let me know if there's anything else I can do to help!
Thanks for the details. So this seems to be a pretty old driver from years ago. While the CPU is old as well, I wonder if current drivers from  would work. Release notes only state SSE4.2 support as requirement.
I guess the driver version should be blacklisted in LibreOffice, too.
I see that the status has been changed to NEEDINFO. What more information is needed?
(In reply to Mike Allen from comment #15)
> I see that the status has been changed to NEEDINFO. What more information is
Would you be willing to try a driver update as suggested in comment 14?
As I explained in comment 8, I'm reluctant to try updating my OpenCL SDK as I don't want to break whichever product is using it. I don't have time to reinstall every piece of simulation software I use, as I have more pressing concerns right now.
Simply having an outdated SDK should not cause LibreOffice to hang - particularly in applications, such as when Writer and Impress, that supposedly do not use OpenCL.
Incidentally, can you explain why the 32-bit LibreOffice runs just fine, while the 64-bit version hangs? If it's because the 64-but version tries to use my OpenCL driver, while the 32-bit version doesn't, then is there a way I can disable use of OpenCL in the 64-bit version to verify whether that is the actually the cause of the hang? At least then I'd know whether it was worth my time updating the OpenCL SDK when I do get the time...
Thanks for your assistance!
Mike, you're absolutely right the old SDK *should* work with LibreOffice. However things often don't work as they should. (otherwise you wouldn't be reluctant to update your SDK, right?) I can't give you an explanation, as I don't have a similar hardware and software configuration to yours, and can't investigate. And unless there's someone who can, and is willing to do that, this issue will not be investigated.
Fortunately it likely can be fixed without that. We can probably safely disable OpenCL in LibreOffice on systems with that driver version.
Tor, what do you think, could this Intel SDK's OpenCL driver be blacklisted?
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?

Apologies for the late reply.
I no longer have access to the machine on which I found this problem. If I get a moment or two, I'll try installing OpenCL on a machine on which I have 64-bit LibreOffice installed and will check to see if I'm still encountering the problem.
Thanks for your assistance!

Confirmed on a Fujitsu Lifebook P771.
Windows 10 Pro x64 1809, build 17763.134
Intel Core i7-2617M vPro (Sandy Bridge) @ 1.50 GHz
Intel HD Graphics 3000 integrated graphics (maybe our culprit), no secondary card
Intel driver 22.214.171.12459 (latest from Windows Update causes blurry text, and the card does show up as "unsupported")
4 GB RAM
Version: 126.96.36.199 (x64)
Build ID: 86daf60bf00efa86ad547e59e09d6bb77c699acb
CPU threads: 4; OS: Windows 10.0; UI render: default;
Locale: en-US (en_US); Calc: threaded
When starting it from a clean install (just reinstalled to upgrade to x64), it hangs on a blank screen when running LibreOffice with 40% CPU usage according to Task Manager. Launching Writer causes a silent background process that apparently restarts itself over and over.
Starting in Safe Mode and disabling hardware acceleration makes things work without issues.
It does appear that OpenGL blacklists the 3000, but OpenCL does not. Perhaps we should blacklist it until we fix it?
Dear Mike Allen,
To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.
There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.
If you have time, please do the following:
Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/
If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.
Please DO NOT
Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not
appropriate in this case)
If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/
2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword
Feel free to come ask questions or to say hello in our QA chat: https://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa
Thank you for helping us make LibreOffice even better for everyone!
I have also had this problem. I am running windows 8.1. I installed the most recent 64 bit version (as of a week ago or so), 7.0.4. I appreciate the humor in you asking for the version from 'about' on an installation that hangs during startup. At the time, my machine had only 4 GB of memory. I don't know if that might be related.
I installed the x86 version and it works fine.
I will supply whatever information I can, but I don't know what would be helpful.

Ron: can you check this?
