Hello TRD and :welcome:

Your screen capture is very much appreciated.

Please carefully read the locked and pinned topic in this sub-forum, How to report a False Positive and for developer analysis, kindly attach the 3 requested .zip archives to your next reply in this thread.

If an exclusion has not already been entered, a temporary exclusion entry might then be made available to prevent a re-occurrence for your individual system.

Thank you for beta testing MBARW and your feedback.

A few notes:

1. not sure that any of the attachments will be of value as I had to update Calibre2 to the latest version in order to recover the ebook viewer

2. additionally, I installed the latest Beta version of MBARW

3. Therefore, both applications are now one version up from the versions where the false positive occurred.

Sorry, I wasn't thinking about sending log files, only recovering the ebook viewer.  in any event all requested files are attached.  I hope this helps

Hello TRD and :welcome:

Since the system in question had MBARW Beta7 installed over the top of Beta6, the cumulative logs were not lost in this case.  :)

Available data strongly suggests a false positive, and if it has not already been done, you may wish to make the following temporary full pathname file entry in MBARW GUI Dashboard -> Exclusions:

                         C:\Program Files\Calibre2\ebook-viewer.exe

At any time, a MBARW development team member, QA team member or Staffer may request the above temporary exclusion be altered/deleted.

Thank you for beta testing MBARW and your valuable feedback.
