32bit and 64bit Widnows system folders


Here are some quick & useful info regarding Windows system folders in 32bit and 64bit:

For 32bit:

%SystemRoot%\system32\

%SystemRoot%\syswow64\


For 64bit:

C:\Windows\system32\

%WinDir%\system32\


For 64bit from 32bit application:

%WinDir%\sysnative\

ExampleWhen accessing Windows 64bit system folder from Visual Studio post build commands (where all versions are actually 32bit), then use %WinDir%\sysnative\ not %WinDir%\system32\.

Hope this helps!

Error: feature with ID is not installed in this farm and cannot be added to this scope


Error:
In Visual Studio 2013 or 2010 when you are trying to deploy your feature (using the default Active Deployment) and your SharePoint farm has a multiple servers, then it will fail to deploy the solution & activate the features, and will throw the following error message:
 Error occurred in deployment step ‘Activate Features’: feature with ID '{guid}' is not installed in this farm, and cannot be added to this scope.
Also, the solution will show ‘Not Deployed’ in Farm solutions page in Central Administration


Reason:
This is a bug in Visual Studio 2013 (see this post for same issue in VS2010). Visual Studio uses the Microsoft.SharePoint.Administration.SPSolution.DeployLocal() method that can only deploy/activate features on local machine when its the only server in farm.


Objective:

To preserve the way the developer works. Developer need not worry about target environment (number of servers in farm for example), and should not need to run PowerShell commands every time the code changes. Developer should only use the Build > Deploy menu item in Visual Studio as usual, and the deploy process should figure it out how to install the package & features.


Solution:

Its actually a workaround until Microsoft fix with their Visual Studio. The idea is to replace Visual Studio feature activation action by a PowerShell script that will make sure the feature was installed then activated properly. The script is to be called as a post-deployment command.


Tested with:

Visual Studio 2013 Update 2, and SharePoint 2013 Visual Web Part


How To Use:
1- Make sure that path of your project does not contain spaces
     Example: “D:\TeamShared\iibraheem\PSproj\PSproj”



2- If you are using Visual Studio 2013 to target SharePoint 2013: Make sure that you set the ‘Site Url’ property of your project to target a SharePoint 2013 site that has the new SP2013 UI.


The reason is that your Visual Studio 2013 visual web part will NOT work for a SharePoint 2013 site that has a SP2010 UI (coming from a SP2010 db upgrade). 3-Adding the script
     3.1-Add the script file (Example: PostDeployScript_Feature.ps1) to project at root level:



     3.2- Edit script file: set the parameters $Url and $FeatureName. $FeatureName is in the format of   ‘ProjectName_FeatureName’ (without quotes) and has nothing to do with feature title 2.


4- Go to project properties > SharePoint tab


    4.1-Set Active Deployment Configuration to ‘No Activation


    4.2- Paste the below command in Post-Deployment Command Line box:

  • Show Then Hide PS console (recommended):
%SystemRoot%\sysnative\WindowsPowerShell\v1.0\powershell "start-process powershell.exe -ArgumentList '$(ProjectDir)PostDeployScript_Feature.ps1'"
  • Keep visible PS console (for debugging):
%SystemRoot%\sysnative\WindowsPowerShell\v1.0\powershell "start-process powershell.exe -ArgumentList '-NoExit', '$(ProjectDir)PostDeployScript_Feature.ps1'"



5- Save the project



6- Build > Deploy

    Check PowerShell console window:
    It stays visible if ‘-NoExit’ parameter used, otherwise it will close automatically:




Now, check the target site for changes:

  • Feature to be added to the required scope (for example a specific site collection)
  • Web part will be added to Web Parts gallery at the site collection
  • Web part can be inserted to page. If previously added to a page, the page will show the updated web part
