Hi guys!
I've a student unlocked Lumia 520 and wanted to install 5 apps using WP Power Tools. I've installed WP SDK 8 Lite.
But when I try the installer, it throws away the error:

"Microsoft,VisualStudio.OLE.Interop Version 7.1.40304.0 be installed in the Global Assembly Cache (GAC) first.

Is there any way to bypass the GAC check? Or do I need to install the whole Visual Studio Exp 2012 again? I've very limited bandwidth left now :( Please tell me what are the exact requirements for WP Power Tools!
Please don't suggest about XAP Deployer, I need to edit my app files more frequently so only WP Tools can help me. Any help would be greatly appreciated :)

You have a solution here: Windows Phone Power Tools - Windows 8.1 fresh install -> Unable to run. Required assembly Microsoft.SmartDevice.Connectivity

Have you tried this: Here are the steps to fix this issue

1. Download the latest source code.
2. In projects WindowsPhone.Tools and WindowsPhonePowerTools, remove the references to Microsoft.Smartdevice.Connectivity.dll and add "C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.SmartDevice.Connectivity\v4.0_11.0.0.0__b03f5f7f11d50a3a\Microsoft.Smartdevice.Connectivity.dll".
3. In project WindowsPhone.Tools, remove the reference to Microsoft.Smartdevice.ConnectivityWrapper.10.dll.
4. In RemoteAppIsoStoreItem.cs, remove “extern alias SmartDeviceConnectivityWrapper10;” at the beginning of the file.
5. Again in RemoteAppIsoStoreItem.cs, find the following code and remove the else statement.
   if (remoteFileObject != null)
   {
   remoteFileObject.GetRemoteIsolatedStorageFile().DeleteFile(_path);
   }else
   {
   …
   }
