SecureBlackbox 16: (VCL) I am getting ‘Error: Unresolved external Cert...’ when linking the project with C++Builder

The error means that Crypt32.lib is not linked to your project. To add Crypt32.lib, do the following:

1. Close the C++Builder IDE (or Borland Developer Studio IDE)
2. Open the BPR file of your project in a text editor (notepad is OK)
3. Find the following line:

   ALLLIB value="..."

4. This line includes the list of the libraries to be linked. Add "crypt32.lib" (without quotes) to the end of this list.
5. Save the project and reopen the IDE.
