As Foxit users who have already updated their current version to the latest version 2.3 build 2825, want to update JPEG 2K/JBJG Image Decoders add-on to the latest one as well by clicking on the "Check for Updates Now" menu of Foxit Reader, they may run into a problem of failing to upgrade.
Here comes the solution to such a problem. Please close Foxit Reader, manually delete the file named fxdecod1.dll under the directory of Foxit Reader, open Foxit Reader again, and then click on "Check for Updates Now" to finish the upgrade again. The problem will be gone.
We plan to publish the bug fix in next release per our development schedule. Thanks for your understanding. Please write to us
support@foxitsoftware.com if you still get any further questions.
Have a nice day!
