We’ve all been there: you click to download an important file, expecting Internet Download Manager (IDM) to swoop in and speed things up, but instead, you’re greeted with the frustrating “Cannot transfer download to IDM” error. It’s a common hiccup that can disrupt your workflow, but the good news is that it’s usually easy to fix.
This error typically means that the main IDM application isn’t running in the background, so your browser has nowhere to “hand off” the download. This can happen if IDM is disabled from your system’s startup list or if certain system optimization tools (like Acer Device Care or other boot-time boosters) are preventing it from launching automatically.
Don’t worry, we’ll walk you through the simple solutions to get IDM running smoothly in the background and make your download experience seamless again.
How to Fix the “Cannot Transfer the Download to IDM” Error
Follow these two proven methods to resolve this issue and get back to downloading at full speed.
Method 1: Enable IDM in Your System’s Startup Programs
The most common reason for this error is that IDM is not set to launch when your computer starts. Here’s how to check and enable it using the Task Manager.
- Step 1: Open the Task Manager by right-clicking on your taskbar and selecting “Task Manager,” or by pressing Ctrl + Shift + Esc.
- Step 2: In the Task Manager window, navigate to the “Startup” tab (or “Startup Apps” in Windows 11).
- Step 3: Look for “IDM” or “Internet Download Manager” in the list of programs.
- Step 4: Check its status. If it says “Disabled,” right-click on it and select “Enable.” This ensures IDM will launch automatically every time you boot up your PC.

Pro Tip:
After enabling IDM in the startup list, it’s a good idea to restart your computer. This will confirm that the setting has been applied correctly and that IDM is running in your system tray before you even open your browser.
Method 2: Configure IDM’s Internal Settings
Sometimes, the setting to launch on startup might be disabled within IDM itself. Let’s make sure everything is configured correctly inside the application.
- Step 1: Open the Internet Download Manager application from your Start Menu or desktop shortcut.
- Step 2: In the main IDM window, click on “Options” from the top menu bar.
- Step 3: In the “General” tab, make sure the following two boxes are checked:
- “Launch Internet Download Manager on startup”
- “Use advanced browser integration”

- Step 4: Click “OK” to save your changes.
- Step 5: Close and restart IDM to ensure the new settings take effect.
Pro Tip:
If you use system optimization tools or “boot boosters,” check their settings. These programs often disable startup applications to speed up boot time. Make sure you add IDM (IDMan.exe) to their “whitelist” or “exceptions” list to prevent them from interfering.
By following the steps outlined above, you can easily configure IDM for optimal performance and say goodbye to the “Cannot transfer download” error. Enjoy fast, reliable, and hassle-free downloads every time!
Frequently Asked Questions (FAQ)
- Why does this error happen even if IDM is installed correctly?This error isn’t about a faulty installation. It’s a communication issue. Your browser tries to pass the download to IDM, but if the IDM application isn’t actively running in the background, there’s nothing to receive it. Enabling it on startup ensures it’s always ready to catch those downloads.
- Do I need to do both methods to fix the problem?It’s best to check both. Method 1 (Task Manager) fixes the issue at the operating system level, while Method 2 (IDM Options) fixes it at the application level. Ensuring both are correctly configured provides the most reliable fix.
- I tried both methods, but the error still appears. What’s next?If the issue persists, try running IDM as an administrator. Right-click the IDM shortcut and select “Run as administrator.” You can also try reinstalling the IDM browser extension. Lastly, check if your antivirus or firewall is blocking IDM—sometimes, they can mistakenly interfere with its processes.
- Does using a ‘boot booster’ program cause this IDM error?Yes, it’s a very common cause. “Boot booster” or “PC optimization” software aggressively disables startup programs to make your computer boot faster. While this can be useful, they often disable essential background apps like IDM. You should go into your optimization software’s settings and specifically allow IDM to run on startup.
