One common concern among users is what happens to their software license when a computer is formatted, Windows is reinstalled, or the application is removed from the system. To address this concern, Smart GST Calculator by BISON stores its license information in a separate license file that can be safely backed up and restored whenever required.

Why License Backup Is Important

Many users periodically:

• Reinstall Windows
• Upgrade SSD or Hard Disk
• Replace hardware components
• Format their computer
• Migrate to a new operating system installation

In such situations, software activation information may be lost if proper backup procedures are not followed.

To prevent unnecessary reactivation requests, Smart GST Calculator by BISON stores activation data inside a dedicated license file that can be preserved and reused after system restoration.

License File Location

The software stores its license information in the currently active Windows user's profile.

Example:

C:\Users\ADMIN\AppData\Roaming\BisonGST\license.dat

Where:

• ADMIN = Windows username
• AppData = Hidden Windows system folder
• Roaming = User-specific application data folder
• BisonGST = Software data folder
• license.dat = License information file

The username may differ on every system.

Examples:

C:\Users\Administrator\AppData\Roaming\BisonGST\license.dat

C:\Users\John\AppData\Roaming\BisonGST\license.dat

C:\Users\Accounts\AppData\Roaming\BisonGST\license.dat

How to Find Your License File

Method 1 – Direct Navigation

1. Open File Explorer.
2. Enable "Hidden Items" from the View menu.
3. Browse to:

%APPDATA%\BisonGST

4. Locate:

license.dat

Method 2 – Using Run Command

1. Press Windows + R.

Recommended Backup Procedure

Before formatting your computer:

1. Open:

2. Copy the file:

3. Save it to:
   • USB Drive
   • External Hard Disk
   • Cloud Storage
   • Email Attachment
   • Network Drive
4. Keep the file secure and confidential.

Restoring License After Windows Reinstallation

After reinstalling Windows:

1. Install Smart GST Calculator by BISON.
2. Launch the software once.
3. Close the application.
4. Open:

%APPDATA%\BisonGST

5. Copy your previously backed-up:

license.dat

The software will automatically detect the existing license and restore activation without requiring manual re-entry of the license key.

Important Requirement

For automatic restoration to work smoothly:

• Use the same Windows user profile whenever possible.
• Example:

Keeping the same username helps maintain consistent profile paths and simplifies license recovery.

What If the Username Changes?

Even if Windows is reinstalled using a different username, the license file can still be restored manually.

C:\Users\ADMIN

New Profile:
C:\Users\Balvinder

into:

and restart the software.
