I need to install this module on my company's intranet, which is DNN 3.3.7.   Because of things beyond my control, I can't upgrade DNN 4.4 right now. I am willing to make changes to get this running on 3.3.7.  I would like to know the best way to  go about this.  After adding the module to the page, I am getting the following error: 

Error: Wiki is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Parser Error: Could not load type 'DotNetNuke.Modules.Wiki.Router'. ---> System.Web.HttpParseException: Parser Error: Could not load type 'DotNetNuke.Modules.Wiki.Router'. ---> System.Web.HttpException: Could not load type 'DotNetNuke.Modules.Wiki.Router'. at System.Web.UI.TemplateParser.GetType(String typeName, Boolean ignoreCase) at System.Web.UI.TemplateParser.ProcessMainDirective(IDictionary mainDirective) at System.Web.UI.TemplateControlParser.ProcessMainDirective(IDictionary mainDirective) at System.Web.UI.TemplateParser.ProcessDirective(String directiveName, IDictionary directive) at System.Web.UI.TemplateControlParser.ProcessDirective(String directiveName, IDictionary directive) at System.Web.UI.TemplateParser.ParseStringInternal(String text) at System.Web.UI.TemplateParser.ParseString(String text, String virtualPath, String basePhysicalDir) --- End of inner exception stack trace --- at System.Web.UI.TemplateParser.ParseString(String text, String virtualPath, String basePhysicalDir) at System.Web.UI.TemplateParser.ParseFile(String filename, String virtualPath) at System.Web.UI.TemplateParser.Parse() at System.Web.UI.TemplateParser.GetParserCacheItemThroughCompilation() at System.Web.UI.TemplateParser.GetParserCacheItemInternal(Boolean fCreateIfNotFound) at System.Web.UI.TemplateParser.GetParserCacheItemWithNewConfigPath() at System.Web.UI.TemplateParser.GetParserCacheItem() at System.Web.UI.TemplateControlParser.CompileAndGetParserCacheItem(String virtualPath, String inputFile, HttpContext context) at System.Web.UI.TemplateControlParser.GetCompiledType(String virtualPath, String inputFile, HttpContext context) at System.Web.UI.UserControlParser.GetCompiledUserControlType(String virtualPath, String inputFile, HttpContext context) at System.Web.UI.TemplateControl.LoadControl(String virtualPath) at DotNetNuke.UI.Skins.Skin.InjectModule(Control objPane, ModuleInfo objModule, PortalSettings PortalSettings) --- End of inner exception stack trace ---

Any information would be helpful

Thanks for your quick response.  I'll try the KTomics Wiki first because I'm still green on compiling the source packages. :)  I'll post my results as soon as I can

You'll need to modify the project references inside the source code to point to your DNN 3.3.7 DLLs instead of the 4.4.1 dlls which it will be looking for.
