Troubleshooting Download Stalls at 99% in Internet Download Manager (IDM)

Many users have encountered a common issue with Internet Download Manager (IDM): downloads get stuck at 99% and do not complete. If you’re experiencing a similar problem—where multiple files pause at near-completion, showing statuses like “Connecting,” “Send GET,” or “Disconnect”—this guide offers insights and practical solutions to resolve the issue efficiently.

Understanding the Issue

IDM is a popular tool for managing and accelerating downloads. However, users sometimes report that while downloads start smoothly, they become stuck at 99%, with progress halting and statuses indicating connection problems. This behavior often occurs when downloading multiple files simultaneously, but it can also happen with a single download.

Common Causes

Server-side limitations: Some websites limit download connections or have restrictions that interfere once a certain percentage is reached.
Firewall or antivirus interference: Security software may interrupt ongoing downloads.
Network instability: Fluctuations in internet connection can cause IDM to lose its connection to the server.
Browser integration issues: Problems with the IDM browser extensions or configurations can disrupt download tasks.
Corrupted temporary files: Damaged or incomplete cache files may cause download stalls.

Step-by-Step Solutions

1. Pause and Resume Downloads

Sometimes, simply pausing all active downloads and then resuming them can resolve temporary connection hiccups. For the download that reached 99%, try stopping it and initiating a restart.

2. Check Network Connectivity

Ensure your internet connection is stable. Restart your router if necessary, and verify that other online activities are functioning correctly.

3. Disable Antivirus and Firewall Temporarily

Security software can sometimes interfere with IDM’s download process. Temporarily disable your antivirus and firewall, then attempt to resume the downloads. Remember to re-enable security features afterward.

4. Update IDM and Browser Extensions

Outdated versions of IDM or its browser extensions can cause compatibility issues:
– Update IDM to the latest version.
– Reinstall or update the IDM browser extension.
– Ensure your browser is up to date.

5. Clear Temporary Files and Cache

Corrupted download cache may hinder progress:
– Go to IDM’s options menu.
– Navigate to “Save to” or “Temporary Directory” settings.
– Clear temporary files manually or refresh the directory.
