Lectora File Associations (AWT Files)

When you first download Lectora Inspire or Publisher or after a major release that requires a new installation, you may notice that your AWT file is no longer associated with Lectora Inspire or Lectora Publisher. This is the case if double-clicking a Lectora AWT file does not automatically launch Lectora. You can easily associate the AWT file extension in Windows by following these steps:

Setting the Default File Association


  1. Make sure you have administrator privileges with your current login or switch to another login that does have admin rights.
  2. Right-click on any AWT file on your computer.
  3. Choose “Open with” from the context menu that appears.
  4. Then select “Choose default program…”.
  5. Select a program from the recommended list of programs or click Browse… to choose a program that isn’t listed. (Lectora is found by default on your C: drive> Program Files>Trivantis. Inside the Trivantis folder, you’ll find a folder (or multiple) associated to Lectora.  Open the appropriate version folder you want to associate to.  Then locate the Lectora.exe.
  6. Make sure the “Always use the selected program to open this kind of file” checkbox is selected
  7. Click OK.

Once you’ve made a selection from the recommended list or browsed for another installed problem, that program will be the default program that opens up all of your Lectora AWT files.

Control Panel

Alternately you can also change the file associations with the Control Panel:

  1. Open the Control Panel, choose Default Programs, and then click “Associate a file type or protocol with a program”.
  2. Find the .AWT file type in the list and click “Change program…”.
  3. Continue steps 5, 6, &7 above.

Once you’ve made a selection from the recommended list or browsed for another installed problem, that program will be the default program that opens up all of your Lectora AWT files

    This is happening to me when I had uninstalled Lectora 16.2 and then installed Lectora 1.02 in Windows 7 Enterprise. The weird thing that happened was the Acrobat was the only option given even if I had chosen another program via “Browse”. I have talked to my IT department and apparently it is known that Acrobat has taken over the file extension. My team is baffled by this.

    Happens to me too after Upgrading from 16 to 17.

    Having admin rights but it does not remember the tool of my choice. What can I do?

    PS: Colleague of mine has the same issue.

    Best, Kai

      It sounds like Windows is having an issue. Windows controls the associations and if it will not remember your selections there must be an issue with your setup or a conflict in your registry.

    OH, I am using V11 and V12, but when i open a AWT (maybe published by v16/ v17), I cannot open it, it pops up error….
    When I download V17 trial, I can open those file, so V12 cannot open V16/v17 ‘s file?

    I am having this problem now after installing Lectora Publisher 18. I have gone through the steps. I have had our help desk take a look, I have uninstalled Lectora 18 and reinstalled it, and yet, Windows 10 will not recognize Lectora 18 as the default file type for .awt files.

    Everything works fine once I get the file open, it is just a hassle having to always select the program to open it with.

    Ditto here. Windows 7, followed all instructions to make the new Lectora 18 the default and computer will not make the change. AWT files still open with Lectora 17.
