Resolving failure to license error code 4--1

Follow the instructions below in the order presented to resolve failure to license error code 4--1.

Often, this error can be resolved by updating your ProSeries software to the latest version:

  1. Open ProSeries.
  2. From the Update menu, select Update Installed Products.
  3. ProSeries will begin downloading any pending product updates.
  4. When the download is complete, click Install Now to apply new updates.

After updating, re-license ProSeries:

  1. Open ProSeries.
  2. From the Tools menu, select License Products.

If the error message is still present, continue with the next section.

Usually, the “ProSeries has failed to license, error code 4--1” notification occurs when you're trying to license ProSeries on a computer where the Internet Explorer browser hasn't enabled the TLS 1.2 security protocol. To resolve it, follow the steps below.

Follow these steps to enable TLS 1.2 security protocol:

  1. In Windows, navigate your Control Panel and select Internet Options from under Network and Internet.
    • You may also use the Search feature on your Windows taskbar to search for “internet options.”
  2. Select the Advanced tab and scroll down to the Security section.
  3. Check the box for TLS 1.2 enabled.
  4. Click OK.
  5. Close Internet Explorer.
  6. Update ProSeries by selecting the Update menu and clicking Update Installed Products.
  7. Re-license ProSeries by selecting the Tools menu and choosing License Products.

If the error message is still present, continue with the next section.

  1. Close ProSeries.
  2. Open Windows File Explorer.
  3. Browse to the following location: C:\ProgramData\Intuit\EntitlementClient.
    • ProgramData is a hidden folder. To view it, you may need to open Control Panel, then select File Explorer Options. Click the View tab, and then check the box labeled Show hidden files, folders, and drives.
  4. Open the v8 folder.
  5. Right-click on the entitlementdatastore.ecml file, then select Rename.
  6. Type old at the end of the file name, so that it reads entitlementdatastore.ecmlold.
  7. Open ProSeries.
  8. From the Tools menu, select License Products.

The entitlementdatastore.ecml file contains the license information for ProSeries 2015-current as well as QuickBooks Desktop. To re-license prior year ProSeries programs go to the Tools menu and select License Products. If you use QuickBooks you will need to go to the Help menu and select Activate QuickBooks Desktop.

If the error message is still present, continue with the next section.

If the 4--1 error code persists after following the steps above, try uninstalling and reinstalling the entitlement client as follows:

  1. Close ProSeries.
  2. Open Windows File Explorer.
  3. Browse to C:\ProWinYY\msiupdates\EntlClnt.msi.
  4. Double-click on the EntlCnt.msi file.
  5. Select the option to Remove ProSeries 20YY Shared Components.
  6. Select Finish, and then click Close.
  7. Double-click on the EntlCnt.msi file to reinstall the components.
  8. Follow the on-screen prompts.

  10. Open ProSeries.
  11. From the Tools menu, select License Products.
