Which version LO installed: 64 or 32

I just upgraded to on a Windows 10 64-bit computer and LibreOffice no longer recognizes the installed Java (which is 64-bit).

It occurred to me that I accidentally installed the 32-bit version of LibreOffice without realizing it. When I look at the download page, the 64-bit version is selected by default. Even though it is unlikely, I still want to check if I have the 32-bit version installed.

When I checked “about LibreOffice”, I expected to see something telling me if the installation is 64 or 32. However, I don’t see such information. How can I find out which version is installed?

Thank you.

The first line in Help-About dialog is either like Version: (without mentioning the bitness - for 32-bit version), or Version: (x64).

32-bit version installs itself into C:\Program Files (x86)\LibreOffice 5 (we speak about 64-bit OS, of course); 64-bit LO is installed into C:\Program Files\LibreOffice 5.

When a 32-bit LO is run on 64-bit OS, task manager of Win10 shows for it: LibreOffice (32-bit) on “Processes” tab.

Thank you, Mike, for answering so completely. I now see that I mistakenly installed the 32-bit version. I should have thought to check where it was installed and the process used before writing for help.

The rationale for not telling us which version it is escapes me. I don’t know if it would be considered a bug report or an enhancement request but I will send some friendly feedback about this.

I hope this information saves me from dealing with Java again!

Well, from a developer’s PoV, it’s simply expected that a user filing an issue just copies all Help-About content verbatim, and posts to us, so we can tell unambiguously. I see that sometimes user can be unaware of their bitness, and also be willing to find it out, so I see your point.

OTOH: it is enough to install both 32- and 64-bit javas in parallel, to avoid the problem. But I prefer 64-bit LO, so it was worth the effort, IMO.

Thanks for the insight, Mike. It is good to know that submitting an issue can be that easy.
Since a developer will read these comments, one more point: Labeling the x64 version x86_64 in the dropdown menu is confusing. I would not know that it is the x64 version unless someone mentioned that here.

I see that I misread what Mike suggested. I thought he said to copy all the content of this post, so my comment doesn’t quite make sense.

Did you keep the installer you downloaded ? If you read x64 in its name it is the 64 bits version, if you read x86 it is the 32 bits version.

Good suggestion. Don’t know why I didn’t think about that.

How the heck does one get the 64 bit Windows version? All I can find is 32 bit.


To the right of the version (e.g., LibreOffice 5.4.1) is the “Choose your operating system:” section.

Please make sure you use English site: some localized versions are not fully up-to-date, and have their own means to provide different bitness versions.

I’m using the English site. Even though the box says “Choose your operating system:”, it is not a hyperlink and the only thing else in that box is the large Download button (which only brings up the 32 bit installer) with two smaller buttons (Torrent and Info) underneath.

What OS and browser are you using?

I’m using Chrome in Win10x64. If you select Windows X86_64, then the DOWNLOAD yellow button should give you the x64 download.

Yet, there are all released versions available here: Index of /libreoffice/old

I finally found the correct page and downloaded it. It’s on the LO website but you can’t get there from the main website address. I had to use my search engine to find the correct page. https://www.libreoffice.org/download/libreoffice-fresh/?type=win-x86_64

We cross posted. I’m using IE11 and that may be the reason the button is missing (I’m also on Win 7)…
