Download TLex Suite (Lexicography, Terminology & Corpus Software)

Software EULA (End User License Agreement) »

TLex Suite includes TLex, tlTerm, tlCorpus and tlReader. (If you purchased "tlTerm Standalone", go here instead)

Please read these instructions carefully. Select a download link below:

News: Version 2022 pre-release available. Now also supports new Macs running on Apple chips.

All existing licenses have been automatically upgraded to the latest. Use your 9-digit License Number to activate (if you've lost yours, try the recovery form). Installs as trial version if unactivated.

Windows (64-bit and 32-bit):

Download: TLex_Suite_Setup_14.1.0.3155.exe

To save the installer file to your hard disk, click on the link with the right mouse button and select "Save Target As". Once you have downloaded the file, run it (e.g. by double-clicking on it) to install the software. (If you already have an older version installed, this installer will automatically first uninstall the previous, and then install itself.)
This single installer installs both 64-bit and 32-bit versions together, and adds extra shortcuts in the Windows Start menu labelled "64-bit" if you want to run 64-bit versions (otherwise by default it runs the 32-bit version). The 32-bit and 64-bit versions are fully compatible with each other. You can use Help/About to see which version you are using.
In general, it is also usually fine to install an older version over a newer version in case you need to revert to an older version.

If SmartScreen pops up with a message about "protecting your PC", click "More Info", then click "Run Anyway" - this is a false alarm from Microsoft SmartScreen. Also please select "Report as Safe" if you see such an option.

▶ [Dec 2021] Announcement for Mac Monterey users: M1 Mac release »

Monterey M1 downloads
Monterey on Apple chip »

If you are using Monterey or higher on an Apple chip (M1), you should use this alternative download. (This build is targeted for the Apple M1, so should not need Apple Rosetta, allowing you to get the most performance-wise from your M1.) Please note this early release may have some aesthetic issues we are working on.

Click the above link, then select the sub-folder with the highest version number to find the .dmg.

Monterey on Intel downloads
Monterey or Big Sur on Intel Macs »

Try this alternative download if you are using Monterey or higher (or Big Sur) on an Intel Mac and the regular download is not working.

Click the above link, then select the sub-folder with the highest version number to find the .dmg.

If you are not sure if your Mac has an Intel or an Apple chip, click the Apple logo menu, select "About This Mac" and check the "Chip".)

▶ If GateKeeper warns it is 'unable to check for malicious software', go to 'System Settings -> Security -> General' and add an exception to allow it to "open anyway" (see Apple site for more info).
If you get a message that the App is "damaged", then try either:
* Run Terminal, and enter: xattr -cr /path/to/TheApplication.app
* or, also in Terminal: sudo xattr -rd com.apple.quarantine /path/to/TheApplication.app
* and/or try rebooting or clearing your cache and re-downloading the DMG. Contact us if that still doesn't work.

macOS 32-bit (old):

Download: TLex_Suite_2019_11.1.0.2625.dmg

[^ final 32-bit version] To install, open the DMG package, and drag the application icons onto your Applications folder.

Software Activation

When you first run the software, it will ask to be activated. Simply follow the activation instructions carefully. You will need your 9-digit License Number (if you have lost or don't know your License Number, click here).

Re-activation is not usually required when updating. NB: If the software will be used by multiple Windows users on the same computer, you may need administrator rights at time of activation.

Evaluation

If you do not have a License Number, you can try out the software by clicking "EVALUATE" (some functional limitations may apply). See "Help/About" for the expiry date. At any time, you can purchase a License Number to activate the software and remove all limitations.

Old-DOM Legacy Version ('Old Document Object Model')

If you are still specially required to use our 'old-DOM version for a particular project, use these download links.

Please note that as of June 2018 fewer than 2% of our active users are still on old-DOM, so we will no longer produce new old-DOM builds; however, we will leave a 'final binary release' online indefinitely, to assist with future conversion and so that users are left 'stuck'. Please contact us if you would like assistance converting your document to the new Document Object Model.

If you want help converting an old-DOM document to new-DOM format, please contact us for a free evaluation of the work: if the work is 'simple' we will do it for free; if it's complex we will provide a quotation.
