# Error - ReferenceError: openLInkPriv is not defined

When a doclink is clicked in a PDF file, the following error message appears:

![](/files/-MlFO14n8Lqd7hoQw-98)

The error is caused due to a missing swpdfc.js file which normally installed in the Adobe Reader installation folder automatically. 

To resolve the issue, create the `swpdfc.js` file (see the code below) and copy it manually to the Adobe Reader installation folder. The default path to the folder is normally "C:\Program Files (x86)\Adobe\Reader 11.0\Reader\Javascripts", however the actual path on your system may be different.

```javascript
var openLinkPriv = app.trustedFunction( function(dbId, docUnid) {
	app.beginPriv();
	try {
		var depth = 50;
		try {
			depth = this.path.split("/").length;
		}
		catch(e) {
		}
		
		var dirUp = "../";
		var xmlRoot = "";
		var xmlFile = "doclinks.xml";
		var xmlStream = null;
		var count = 0;
		do {
			try {
				xmlStream = util.readFileIntoStream(xmlFile);
			} catch(e) {
				xmlStream = null;
			}
			
			if(xmlStream == null) {
				xmlRoot = dirUp.concat(xmlRoot);
				xmlFile = dirUp.concat(xmlFile);
			}
			
			count++;
		} while(xmlStream == null && count < depth);
		
		if (xmlStream == null) {
			app.alert("XML not found");
			return;
		}
		
		var xml = XMLData.parse(util.stringFromStream(xmlStream), false);
		var xPath = "string(//data/element[@id = '";
		xPath = xPath.concat(dbId);
		xPath = xPath.concat("-");
		xPath = xPath.concat(docUnid);
		xPath = xPath.concat("']/location)");
		var location = XMLData.applyXPath(xml, xPath);
		location = xmlRoot.concat(location);
		app.openDoc(location);
	} catch(e) {
		app.alert("Linked document could not be found: " + location);
	}
	app.endPriv();
});
```
