If you searched for "all images downloader unlock code" because Image Downloader Pro stopped activating or a premium feature shows locked, do not paste a code from an uncertain site. This troubleshooting playbook explains the common causes, shows the screens and settings to check first, and lists practical fixes I use as a private image collector. Start with the store restore steps, then move down the list if those do not work. For official downloads and docs see the product page Image Downloader Pro and the documentation Image Downloader Pro documentation.
Short answer: avoid unofficial codes and try these steps in order
When activation fails, the most likely causes are a mismatch between installed extension copy and the store account, a failed restore call, a network block, or a different account used at purchase. Follow these steps in order. If you purchased through the browser store or the vendor site, you can usually restore access without any third-party code.
Symptom 1 - The extension shows "locked" after purchase
Quick diagnosis
- You completed payment but the popup still shows locked features.
- The extension was updated, reinstalled, or installed from developer mode after purchase.
Fixes in decision order
- Open the extension popup and click any "Restore purchase" or "Sign in" button. Some purchases require a one-time restore call from the popup to mark the install as licensed.
- Close and restart the browser. Some license flags are applied only after the browser restarts.
- Confirm you installed the extension from the same store used for the purchase. If you bought from the Chrome Web Store, the Chrome-installed copy must be linked to the same store account.
- If the copy was installed in developer mode or from a downloaded build, remove that installation and install the store-listed extension. Developer-mode installs do not always inherit store purchases.
Symptom 2 - Activation error says "invalid code" or "not recognized"
Why that happens
- Most modern extension licensing uses the store account or a restore endpoint rather than manual codes. A code copied from a forum is frequently invalid or expired.
- If the product supports redeemable codes, typing mistakes, extra spaces, or line breaks during copy and paste cause failures.
Fixes
- If you received a code in an email, type it manually into the field and watch for similar characters such as capital O versus zero and uppercase I versus lowercase l.
- If the purchase email includes a restore link or an instruction to sign into the store account, follow that method instead of pasting a code.
- Search your email receipt for exact instructions used at purchase. Store receipts often provide a restore link or rely on your store-account state instead of a transferable code.
Symptom 3 - The extension reports network or server errors during restore
Common causes
- A firewall, network-level adblocker, or privacy extension is blocking outbound calls the extension uses to verify purchases.
- Your browser or device is offline when the verification call runs, or a corporate proxy is interfering with the request.
Fixes
- Temporarily disable restrictive extensions such as network adblockers and retry the restore flow.
- Try the restore on a consumer network or tether to your phone to rule out corporate proxy restrictions.
- Check the OS firewall settings and any browser prompts that might block the connection. Allow the browser to make outbound connections if prompted.
Symptom 4 - You used a different account to buy
What to check
- Browser store purchases are tied to the store account that made the payment. They are not automatically linked to any email you enter inside the extension unless you explicitly tied them together during purchase.
Fixes
- Open the browser store where you purchased (for example, the Chrome Web Store, Edge Add-ons, or Firefox Add-ons) and confirm which account shows the purchase.
- Sign into that same store account in the browser on the device, reinstall the extension from the store if needed, and restart the browser so the store state flags the extension as licensed.
Decision aid - choose the right path
Answer these three quick questions to choose the path I would follow as a collector:
- Did you buy from a browser store? If yes, restore from that store account first.
- Did you reinstall or switch browsers after purchase? If yes, reinstall from the same store and run restore next.
- Are you on a corporate network or behind a VPN? If yes, test the restore on a consumer network before contacting support.
Why searching for an "unlock code" is risky
Looking for an unlock code on forums or cracked sites can lead to malware, revoked access, or unstable installs. For private image collectors, keeping a clean local library and a safe workflow is more important than attempting an unofficial bypass. If cost is the issue, try the extension free workflows first. Image Downloader Pro can scan browser-accessible images on the current page and let you preview and save images locally. Some export or ZIP behaviors and advanced renaming or duplicate controls are behind Premium; the extension will still perform many local scanning and saving tasks without a license.
What to include when contacting official support
If the steps above do not restore your purchase, prepare the following to speed resolution:
- Which store and the account used to purchase (for example Chrome Web Store or Edge Add-ons).
- Your receipt or order confirmation email with the date and any transaction ID you received.
- A screenshot of the extension popup showing the locked feature and the exact error text.
- The extension version and browser version. Open chrome://extensions or edge://extensions and note the extension version and the browser version shown in browser settings.
Short-term workarounds while support responds
While you wait for a license restore or vendor reply, these practical workarounds preserve your collecting workflow:
- Use the local-free workflow to scan and save visible images on the page. The extension scans many images discovered after scrolling or interaction, and it supports filters for width, height, file type, size, and orientation so you can curate results before saving.
- Download priority images individually rather than waiting for batch exports. Preview and save the highest-priority images first so you do not lose them.
- Export what you can manually: if ZIP or CSV exports are behind Premium and unavailable, save files and create your own CSV with filenames and URLs. The extension can export a CSV with selectable columns when available, but you can copy URL and metadata into a spreadsheet if needed.
- Use screen captures only when necessary, and record provenance such as the page URL and date in a note. Screenshots reduce resolution and lose original file metadata.
Final checklist to try now
Follow this short checklist in order and stop when the feature unlocks:
- Sign into the browser store account used at purchase.
- Install or reinstall the extension from that store account.
- Open the extension popup and tap Restore purchase or Sign in.
- Disable restrictive extensions temporarily and retry if the restore reports a network error.
- Restart the browser and try again.
If these steps do not restore Premium features, gather the store receipt, a screenshot of the error, and your extension and browser versions, and contact official support with those items. Avoid using codes from unknown sites; they often do not work and can introduce risk to your browser environment.
Ready to try restoring now? Reinstall from the store you purchased from, sign into that account, disable adblockers briefly, and press Restore in the extension popup. For download and restore help, start at the product page: Image Downloader Pro.
Pro tip: Test the workflow on a small batch first. It is easier to adjust filters and filenames before starting a larger download.
