Go to %localappdata%\LyndaCoursesDownloader\app-1.0.0\logs and upload the latest log.txt file here. Does this error happen everytime? Onetime occurenece? Happens with a specific course?

I also have this error using Firefox, on some specific courses ( I didn't take note of which). Switching to Chrome (using slow method) it works for the same course that had the error on Firefox.

@edwardwong75 If you encounter this error again, could you go to %localappdata%\LyndaCoursesDownloader\app-1.0.0\logs and upload the latest log.txt file here.

log20200717.txt I used Firefox to download some courses. I did not get an error prompt, but the last course just hung halfway through extraction (didn't move for more than 10 minutes). I closed the program and uploaded the log file for you. I noticed that Firefox always generates errors during extraction (but can successfully download the files after several retries). Chrome always works flawlessly (although you have to leave the Chrome window open to do the automated extraction).

Thanks for the info. I have a question. I think 4gb of ram or less causes errors especially with firefox but I want to make sure. So, How many gigabytes of Ram do u have and what is the ram speed? You can find out in task manager > Performance > Memory

I have 16GB ram, DDR4 1300mhz (this is a Lenovo laptop).

Then probably the ram is not the problem. I tested the app on a 4gb machine with 2 cores and I had an error nearly every time. Maybe the problem is with the number of cores in the processor. How many cores does your processor have?

edwardwong75 commented 4 years ago

My CPU has 4 cores (8 threads).

I am now working on a new extraction system that will dramatically decrease errors occurences
