How to Remove an Old Activation Key from a Third-Party Excel Application
Question details
The user needs to clear an old activation key from a compiled, third-party Excel application to force the software to prompt for a new activation key.
- Product
- Third-Party Excel Application (XLS Padlock)
- Device & OS
- Windows 10
- Scenario
- After a Windows update, a company-provided Excel executable relies on an outdated activation key. The user has a new executable and key, but the software bypasses the activation screen.
- Observed behavior
- The application attempts to use the previously stored license key, fails to prompt for the new activation key, and subsequently crashes upon launch.
Ensure you have administrative privileges on your Windows PC and have your new activation key and system ID handy before attempting to reset software licenses.
Contact IT or the Vendor for a License Reset Tool
Since the application uses strict DRM tied to your hardware ID, standard uninstallation cannot clear the secure registry keys.
Software compiled with tools like XLS Padlock stores licensing information securely deep within the system to prevent tampering. When a Windows update changes your system or hardware ID, the old stored key becomes invalid but remains undetected by simple file deletion.
To properly remove the old key and trigger the activation prompt again, you typically need a specific registry cleaner or reset utility provided directly by the author of the compiled workbook.
Contact your company's IT department or the vendor who provided the compiled Excel executable.
Inform them that a Windows update altered your system ID, and the software crashes without prompting for the new key because it is reading the old cached license.
Ask for the official license reset utility or detailed registry path instructions specific to their software's configuration.
Run the provided reset tool as an Administrator, reboot your computer, then launch the new executable to enter your updated activation key.
Manually Clear Application Temp Data and Registry Entries
Attempt to manually locate and remove leftover files or registry keys that might be caching the old activation state.

Frequently Asked Questions
Why doesn't deleting the .exe file remove the old activation key?
Compiled applications like those using XLS Padlock store license information securely in the Windows Registry or hidden system folders. Deleting just the executable file leaves the underlying license data intact.
Can a Windows update really change my hardware or system ID?
Yes, major Windows feature updates can sometimes alter how the operating system reports underlying hardware configurations, causing strict DRM or licensing software to think it has been moved to a new machine.
How do I find my new system ID to get a replacement key?
Usually, when a hardware-locked application fails to activate properly, it displays a dialog box showing your current system ID. If the app crashes instantly, you may need to ask your IT department for a diagnostic tool to retrieve the new ID.
