Hello, I use Inno setup to create an installer for my application. The application is used by more than 1000 people and I haven't received any messages about installation problems before, but now somebody says he gets the following error when using my app.

Code:
Runtime error 339 - Component 'mswinsck.ocx' or one of its dependencies not correctly registered: a file is missing or invalid.
mswinsck.ocx is included in the installer and even the Package & Deployment Wizard doesn't show any extra dependencies. Should wsock32.dll be included in the installer as well? I don't know which OS is used, but I can ask.

This is the line in the script. Is something wrong with that line?

Code:
Source: F:\Upload\Setup\VBFiles\mswinsck.ocx; DestDir: {sys}; Flags:  regserver restartreplace sharedfile uninsneveruninstall noregerror onlyifdoesntexist;
