Issue
I'm getting the following error message at Windows startup:
BCHelpere - system error
The program can't start because sqlite3.dll is missing your computer. Try reinstalling the program to fix this problem.
Solution
You have to uninstall/reinstall the application.
As a first step. Search on your HDD to see that if the DLL is really missing.
Click on Start > Run > Type "cmd"
Enter this command and validate (assuming that the application is installed on drive C) attrib c:sqlite3.dll /S
If found, Windows displays the path to the file, you simply have to the instructions given here.
In the other case, download the missing file: sqlite3.dll
Thanks to Pierrot6150 for this tip.
