We have tried the Meg menu and anywhere sliders plugins but they won't install on our nop installation:

Our system info is:
nopCommerce version:   2.70
Operating system:   Microsoft Windows NT 6.0.6002 Service Pack 2
ASP.NET info:   v4.0.30319

We have:
1.  uploaded the plugins int the the plugins directoyr eg: plugins/SevenSpikes.Nop.Plugins.AnywhereSliders  
2. restarted application
3. Tried moving the nop.Web.dll file in the bin directory
4. Even changed the txt file InstalledPlugins.txt in AppData folder and this partially worked but was a last resort and the plugins did not work anyway.

Can someone please suggest a solution?

Thanks Heaps.
