TLex Suite 15 Windows:

Download: TLex_Suite_Setup_15.1.0.3571.exe
Download for Windows

Windows Instructions: 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 (the 64-bit version just allows loading of massive datasets). 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.

TLex Suite 15 Apple macOS

Download: TLex_Suite_2023_15.1.0.3577.dmg
Download for Intel-based Apple Macs

Download: TLex_Suite_2023_15.1.0.3576.dmg
Download for Apple Chip Macs

macOS Instructions:
▶ We have 2 download options, depending on your Mac. In general, if you have an Intel-based Mac you should use the Intel download. If you have a Mac with an Apple chip (M1/M2 etc., also known as arm64), please use the other download option - the Apple Chip build is targeted for the Apple M1/M2 etc., so should not need Apple Rosetta, allowing you to get the most performance-wise from your Apple Chip.

If you are not sure what type of Mac you have, click the Apple logo menu and select "About This Mac", and check the "Chip" or macOS version.

To install, double-click the DMG package, and drag the application icons onto the Applications folder.

▶ 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 this article for more info - also if you get a message saying the App is "damaged")

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.

For 64-bit macOS versions (Catalina etc.), click here, then enter the sub-folder with the highest 4-digit build number, then download the desired DMG, then drag the application icons onto your Applications folder.
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.
Please note that for our 32-bit macOS release line, the final version will be version 2019 - you can still use it on 32-bit-compatible macOS systems, but we will include new features only in our new 64-bit (Catalina-ready) release line.

7.1 / 8.1 / 9.1 / 10.1 = Primary/Official TLex ('New Document Object Model')
