  • Security warning "opened by app without a valid signature" is shown again and again

    Dear FoxitReader support team,

    When I launch PDF from Far Manager, FoxitReader v8.2.0.2051 shows the following message:

    Click image for larger version

Name:	FoxitReader_app.png
Views:	1
Size:	14.7 KB
ID:	166134

    I check the checkbox "Remember your choice" and click "OK". However when I launch another PDF, the same warning is shown again. Also when I modify PDF, it is shown again.

    Can this confirmation be remembered once and forever?

      I have this problem when I open a PDF from Launchy. I check the "remember" box but it does not remember. I have the latest version of Foxit Reader 9.0.1, which I just downloaded today.

            I was facing the same problem FoxitReader v8.2.0.2051. I upgraded my version to Foxit Reader 9.0.1. However, I was facing the same problem again, so what I did, uninstall the software and again install the Foxit Reader 9.0.1. Now it is working properly.

              Dear Lisa,

              Sorry for the delayed response. I had stopped checking for an answer. In answer to your questions:

              1. Windows 10 64-bit
              2. I don't remember from where I downloaded Launchy - I've had it for years and it works well, so I'd rather not reinstall
              3. The C:\Users\Public\Foxit Software\Foxit PhantomPDF folder is empty, except for a sub-folder ("StartPage") - maybe this is the problem
              4. I've attached the registry download (I had to change the extension to .txt from .reg because the browser said I am not allowed to upload .reg files).

              I saw the kevinwalker above solved the problem by reinstalling. I'd rather not do that, because I spent a while setting all of my preferences and don't want to have to repeat this work.

                  Thanks again, Lisa. I installed the newer version from the link you provided. Unfortunately, it still did not solve the problem. The C:\Users\Public\Foxit Software\Foxit PhantomPDF folder is still empty, except for a sub-folder ("StartPage").

                    Mark Rook ,Dear Mark Rook,I am sorry that the location for finding "TrustApp.xml" that I have sent is for Foxit PhantomPDF application.
                    For Foxit Reader,you have to find the "TrustApp.xml" file under:
                    "C:\Users\Public\Foxit Software\Foxit Reader"
                    And please also help to go to "Help"tab in Foxit Reader>"Preferences">"Trust Manager",click on "Change settings..."button under the "Open Foxit Reader from applications without valid digital signatures"to open the"Trusted Apps..."to see if the "Launchy" is already listed in the Trusted apps?
                    If so,please help to manually input your "Launchy" applicatio location there.For example,I have "Launchy" installed under "C:\Program Files (x86)\Launchy" this folder,so I iniput
                    "C:\Program Files (x86)\Launchy\Launchy.exe"in the allowed apps field,click on "Allow"to add it,click on "OK""OK"to save the setting.
                    Then please close and reopen your Foxit Reader to open the "Preferences"dialog box to double check if the "Launchy" application has already been added in trusted apps successfully?
