Can i install / use nuget if my documents folder is on a shared drive?

Question

I see a number of issues on the nuget forum around not being able to install if your My documents folder is on a shared drive. If I don't have the flexibility to change this (locked down policy) is there any way i can use nuget?

Here is the error i get when trying to install it from the VS Extension Manager:

The system cannot find the path specified. (Exception from HRESULT:

The VS log file shows:

Answer 1

I was facing a similar issue and the various suggestions about CasPol and loadFromRemoteSources failed; here's what worked for me (on Windows 7 sp1):

1. Uninstall the current NuGet extension
2. Close Visual Studio
3. Open up a registry editor and navigate to HKEY_CURRENT-USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\
   • The Personal key will show the shared folder as its value
4. Amend that value to a local drive location, e.g. C:\Temp\
   • Don't close regedit as you'll be changing it back in a moment
5. Open Visual Studio
   • it might complain about not finding certain settings, but I just clicked through the warnings
6. Install the NuGet extension
   • at least for me, this all happened smoothly in exactly the way that wasn't happening before
7. Quit Visual Studio
8. Revert the Personal registry value back to its previous state
9. Restart Visual Studio
   • ... et voilà!

I don't tested this myself, but you can try to modify C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe.config file and include loadFromRemoteSources element:

<loadFromRemoteSources enabled="true"/>

at the location <configuration> \ <runtime>. Additionally you can try to verify that no other old version NuGet is installed. You should start Visual Studio 2010 shortcut with context menu and choose "Run as administrator" to be sure that you can uninstall it.

Additionally you can consider to add "FullTrust" to the share for the .NET

CasPol.exe -m -ag 1.2 -url file://ServerName/ShareName/* FullTrust
