I am using a regular system, nothing virtual, my C drive is not mapped which I see in some forums. Environment path not set?

I started a tutorial to learn Powershell, and the first thing I tried to execute was very simple:

PS C:\Users\user> get-help get

Error I receive:

get-help : Cannot find drive. A drive with the name '.C' does not exist.
At line:1 char:1
+ get-help get
+ ~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (.C:String) [Get-Help], DriveNotFoundException
    + FullyQualifiedErrorId : DriveNotFound,Microsoft.PowerShell.Commands.GetHelpCommand

System:
Windows7, Powershell 4.0, .NET 4.5

  • Notice how it says .C. That's certainly not what a valid drive letter looks like. Did you make any changes that could have caused this? – Daniel B Jan 3 '16 at 22:46
  • Have you changed any of the powershell config files? For example C:\Users\{username}\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1? – DavidPostill Jan 3 '16 at 22:51
  • @DavidPostill All I did was install the required files from the microsoft website and tried to execute this line. I did not configure anything or touch any files that were installed. Simply run(cmd) then powershell just as the image demonstrates. Nothing else. – ejbytes Jan 3 '16 at 23:02
  • General: What is with the down voting? Someone is on a spree of bad manners today. I checked out the question board and there are like 20 -1's in a row. Someone had too much to drink I think. Something wrong with the way I posed this question? Please do comment. – ejbytes Jan 3 '16 at 23:03
  • @ejbytes Did you reboot after installing? I recall mine misbehaving after installing version 4.0 (it displayed the wrong version number until I rebooted). – DavidPostill Jan 3 '16 at 23:06

So it seems that I had a bug in my Environment Variables, Path. Here is the screen shot of what I changed.

After trying to reboot and fail. Uninstalled .NET, reinstalled .NET, reinstalled a Powershell version and still fail. I ended up checking my Environment Variables. I had changed them a few years ago per a "fix" for JUNIT testing in Java programming.

get-help : Cannot find drive. A drive with the name '.C' does not exist.

Your PowerShell installation is broken or mis-configured.

It should produce output similar to the following:

PS C:\Windows\System32\WindowsPowerShell\v1.0> get-help get

Name                              Category  Module                    Synopsis
----                              --------  ------                    --------
Get-Verb                          Function
Get-FileHash                      Function  Microsoft.PowerShell.U... ...
Get-Command                       Cmdlet    Microsoft.PowerShell.Core ...
Get-Module                        Cmdlet    Microsoft.PowerShell.Core ...
Get-Help                          Cmdlet    Microsoft.PowerShell.Core ...
Get-History                       Cmdlet    Microsoft.PowerShell.Core ...
Get-PSSessionConfiguration        Cmdlet    Microsoft.PowerShell.Core ...
Get-PSSession                     Cmdlet    Microsoft.PowerShell.Core ...
...
  • I realized that this is the desired output. It's a fresh install. What would cause this error? – ejbytes Jan 3 '16 at 22:59
  • @ejbytes Have you changed any of the powershell config files? For example C:\Users\{username}\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1 – DavidPostill Jan 3 '16 at 23:00
  • No. I didn't configure anything. I am a noob for Powershell and Admin functions. – ejbytes Jan 3 '16 at 23:11
