# ONLYOFFICE Application: Ascensio System SIA Also called only office, onlyoffice desktop editors Ascensio System SIA, Productivity An office suite aimed at Microsoft format fidelity and docs servers. The Windows desktop process is DesktopEditors.exe. It is not LibreOffice. ## What you need to know ONLYOFFICE is DesktopEditors.exe. LibreOffice is soffice.exe. Ascensio ships editors that target Microsoft formats and an optional Docs server. LibreOffice is The Document Foundation's suite. Mixing the two names does not merge the installers. - **What is it?**: Office suite **Still current?**: Yes, see Current status **Official download?**: Use the vendor link in this article Feex says If the window looks like Word but the process is DesktopEditors.exe, this is ONLYOFFICE, not LibreOffice and not WINWORD. I would not repair Office to fix this installer. ## What is ONLYOFFICE? ONLYOFFICE Desktop Editors is Ascensio's Windows app for documents, sheets, and slides. DesktopEditors.exe is the process. LibreOffice uses soffice.exe. They do not share a codebase. ## If you have never used it If you want desktop editors that try to look and save like Word, Excel, and PowerPoint, this is ONLYOFFICE Desktop Editors, not LibreOffice. Download DesktopEditors from onlyoffice.com/download-desktop.aspx. LibreOffice is an OpenDocument-first suite from TDF. ONLYOFFICE is a different vendor that also sells a Docs server. ## What is it used for? **DOCX, XLSX, PPTX editing** The desktop app's selling point is Microsoft-format fidelity. LibreOffice can open those files too. This is a different engine. **Connect to an ONLYOFFICE Docs server** Some teams point the desktop client at a self-hosted Docs host. That is not a LibreOffice remote. **Plugins and local files** Edit on disk without a 365 account. A workplace that mandates WINWORD still wants Word. ## Who is it for? - People who want MS-like editors without Microsoft 365 - Admins who already run ONLYOFFICE Docs - Anyone who should not install LibreOffice thinking it is this exe ## Current status Actively developed. Community and Enterprise Desktop Editors exist. This article is the Windows desktop app. ## How old is it? ONLYOFFICE (TeamLab) began around 2009. Desktop Editors are the local window. The Docs server is how some Nextcloud and company sites embed the same editors. It is newer than OpenOffice.org and not a LibreOffice fork. ## Versions Major channels first. Exact build numbers are not all verified here. Desktop Editors Community Desktop Editors Enterprise Docs server ## System requirements Values follow the publisher's public guidance. Workload still changes the real need. ### Minimum | Operating system | A current supported Windows 10 or Windows 11 release, per the vendor | | ---------------- | -------------------------------------------------------------------- | | RAM | Enough for Windows plus this app. Heavy projects want more. | ## Resource profile - **CPU demand**: Follows what you open inside the app **RAM demand**: Follows documents, tabs, or libraries ## Installed processes These executables belong to this product when it is installed. | DesktopEditors.exe | Windows desktop editors | | ------------------ | ----------------------- | ## Startup components Desktop Editors start when you open a file. They should not replace OneDrive as a sync client. ## File locations | Typical install | C:\Program Files\ONLYOFFICE\DesktopEditors\DesktopEditors.exe | | --------------- | ------------------------------------------------------------- | ## File formats DOCX, XLSX, PPTX, ODT, PDF ## Common problems ### People install LibreOffice when they were told ONLYOFFICE Different vendor, different exe, different UI. Check DesktopEditors.exe versus soffice.exe. ### Server connection fails The desktop app can work offline. A Docs URL error is a server setting, not a Windows Office repair. ## Getting unstuck ### Open file location on DesktopEditors.exe ONLYOFFICE lives under Program Files\ONLYOFFICE. LibreOffice lives under Program Files\LibreOffice. ### Install from onlyoffice.com/download-desktop.aspx A "free Office editors" search ad is the wrong file. ### If a workplace file must stay in desktop Word, use Word Fidelity is the goal, not a guarantee for every macro-enabled template. ## Alternatives LibreOffice, Microsoft 365, and WPS Office overlap. LibreOffice is not this product. Word remains the reference for some work templates. ## Official help and downloads Start with the vendor. Random exe sites are not a support channel. | Download | [www.onlyoffice.com/download-desktop.aspx ](https://www.onlyoffice.com/download-desktop.aspx)Official installer or vendor page | | ------------- | ------------------------------------------------------------------------------------------------------------------------------ | | Help | [helpcenter.onlyoffice.com/ ](https://helpcenter.onlyoffice.com/)Vendor support | | Official site | [www.onlyoffice.com/ ](https://www.onlyoffice.com/)Start here, not a random exe host | ## Related hardware The desktop editors are Chromium-based and want more RAM than a tiny native suite.
