I am also having this problem. It appears to be related to an issue where the dnvm.ps1 script does not quote the install path. The command dnvm install "C:\Program Files (x86)\Microsoft Web Tools\DNX\dnx-clr-win-x86.1.0.0-beta5.nupkg" from Visual Studio gets recalled as dnvm-install C:\Program Files (x86)\Microsoft Web Tools\DNX\dnx-clr-win-x86.1.0.0-beta5.nupkg, which breaks as the path should be quoted. More information is available on the pull request I opened at:

As a workaround, the solution for me was to change the following in "C:\Program Files\Microsoft DNX\Dnvm\dnvm.ps1". This loops through the arguments, ensuring that any containing whitespace or parenthesis are quoted.

Replace the following line:

$cmdargs = @($args[1..($args.Length-1)])

with:

# Combine arguments, ensuring any containing whitespace or parenthesis are correctly quoted 
ForEach ($arg In $args[1..($args.Length-1)]) {
    if ($arg -match "[\s\(\)]") {
        $cmdargs += """$arg"""
    } else {
        $cmdargs += $arg
    }
    $cmdargs += " "
}

If you are still having issues following making this change, delete C:\Users\username\.dnx and reopen Visual Studio to let Visual Studio recreate the folder.
