System.IO.PathTooLongException when installing JetBrains ReSharper 6.1 build 6.1.37.86 in VS 2011 Developer Preview

I realize that ReSharper 6.1 for Visual Studio 11 Developer Preview is not supported, so if nobody has the answer for the following issue, I'll understand.

I attempted to install ReSharper.v6.1.37.86.vs11.0.vsix into Visual Studio 11 Developer Preview and received the following error (twice, so it wasn't one-time fluke):

Is there a way to fix this issue?  If so, how?
