It's the joy of permissions. Good old Internet Explorer won't let you just install any old thing so although you're giving it the OK to install the plugin, it won't let you regardless. There is a solution though. Grab the .cab file from your episerver install (mine was at C:\Program Files (x86)\EPiServer\CMS\6.1.379.0\Application\UI\CMS\ActiveX\EPiServerClientComponents.CAB )
Extract it as you would a zip file (using your favourite zip-like tool) into a temporary folder. Then create a batch file (just a text file with the extension bat, like install.bat) with the following code:
regsvr32 "My temporary folder location\EPiOfficeIntegration.dll"
regsvr32 "My temporary folder location\EPiFileUpload.dll"
You don't need the first line if you're using a 32 bit operating system. Now right click the batch file and select 'Run As Administrator'. You should get a command prompt telling you the services are registered successfully. Go back to your Components folder, refresh and hey presto, you have the components installed! :)
Im trying to set the CMS up to allow multiple file uploads but there seems to be an issue with the Active X. When I go into the Components section of My Settings to enable the multiple file upload it says "you are using version N/A of EPiServer Client
Components" - Install version 2.3 - I click on this button and a pop up appears - After clicking Install via another popup it goes no where but has a blank popup window. Is there anything I need to do?
I have tried altering my Internet Security settings but nothing has helped.
