Japanese versions of Adobe Reader hang after the trial link appears in the right pane
The Japanese versions of Adobe Reader stop responding after the free trial link with garbled text appears in the right pane.
Adobe periodically surfaces in-product messages for users to drive user engagement. During one of the recent changes, an in-product message that was meant only for users on the latest version of Reader was erroneously sent out to all users.
Adobe reverted the Reader in-product message change immediately after this problem was reported on September 2, 2020. The change becomes effective in 24 hours. Therefore, the problem will be automatically resolved by September 3, 2020.
Meanwhile, you can follow the workaround below to fix the problem.
The in-product messages are stored in the following local application folder on the users’ computer:
To fix the problem, delete the folder and relaunch Reader.
