Common Questions
Quick answers to get you started with VBA Padlock.
What is VBA Padlock?
VBA Padlock is a compiler and protection system for Microsoft Office VBA code. It compiles your VBA macros from Excel, Word, Access, and PowerPoint into secure, obfuscated DLLs with integrated licensing and activation systems — preventing unauthorized access to your source code and letting you sell your VBA applications commercially.
Which Office applications does VBA Padlock support?
VBA Padlock supports all major Microsoft Office applications: Excel (workbooks and .xlam add-ins), Word (documents and templates), Access (databases), and PowerPoint (presentations and add-ins). Your compiled VBA code retains full access to each application's COM object model, so all existing functionality is preserved.
How does VBA Padlock protect my code?
VBA Padlock compiles your VBA source code into native DLLs (both 32-bit and 64-bit). The original VBA code is transformed into compiled bytecode that cannot be decompiled back to the original source. The compiled DLLs include multiple layers of obfuscation and built-in integrity checks that detect any tampering attempts. Your original VBA source code is physically removed from the Office file — only a lightweight VBA bridge module remains.
Do my end users need VBA Padlock installed?
No. End users only need Microsoft Office installed on their computer. The compiled DLLs and a small VBA bridge module are all that's needed to run your protected code. VBA Padlock is only required on the developer's machine for compilation.
