After completing a file download, IDM joins all downloaded parts into a single file and then writes the real file to the hard drive, and shows ‘download complete’ dialog. IDM does this normally to any file. With some security applications like Antivirus/Firewall/ Internet Security, you may get an error when IDM tries to write the file to the disk.
Here is that error: ‘An error occurred during download. Please try again’ Details:Cannot open local file for writing while joining downloaded parts into one file’.
Panda Free Antivirus blocks IDM from writing the file to the disk
No matter how may times you try to resume the download again, it doesn’t finish, you’ll receive the same error.
We’ve found the Panda Free Antivirus installed on our computer as the culprit for this, we tried to download the file again after disabling Panda Free AV, it worked.
SEE: Fix IDM Setup’s Error ‘Could Not create process in unpacker Access is denied. ‘
If you’ve got this type of error with IDM (check the update added below), try to download the file by temporarily disabling antivirus or other security application you’re using on your system.
UPDATE: Latest Panda Free Antivirus 2016 v16.0.2 no longer blocks IDM file writings to the disk, so the issue has been fixed.
Can anyone suggest a fix for this? I have Panda installed on another machine and it doesn’t interfere. With this machine, however, every time I use IDM I have to disable Panda.
I can confirm Panda Free Antivirus 2016 has caused this on my machine, other than disabling Panda for that time, we couldn’t found any fix, in fact we’ve switched to built-in Windows Defender.
It literally took me 30 seconds to resolve this issue. Hasn’t anyone looked into this?
It’s because IDM Saves to a Temp Directory under AppData\Temp
Simple change the Temp Directory which is under Configuration > Save to
I created a Temp Folder under Downloads and it resolved the issue immediately.
IDM saving to temp directory is normal, but the latest Panda Free Antivirus v16.0.2 no longer blocking IDM from writing files to hard drive. Thanks for sharing the workaround anyway.
I have the same problem and I’m running Panda 2016 (16.0.2) and IDM (6.25 build 3), so the issue has obviously not been fixed. Stopping Panda allows IDM to finish the download. It appears to not affect all downloads all the time. I was able to download HP printer drivers (first attempt failed, but upon resume it completed), Chrome and other stuff without this problem, but Adobe Flash Player did not complete no matter how many times I tried, until i stopped Panda and the download completed! Mysteriously enough, I have a second machine running Panda 2016 (16.0.1) and IDM 6.23 build 18 and doesn’t have this problem. Adding the whole of IDM’s installation folder to Panda’s exclusion does not change anything. Changing IDM’s save to temp folder doesn’t help either. I’m suspecting it’s Panda’s Heuristics or behaviour analysis, but it doesn’t explain why it affects one system and not another of the same setup. Will try adding IDM’s temp folder to Panda’s exclusions and try again.
It Worked
i disabled panda AV…
