If
you are looking to manually install or uninstall a Web Part, you’re unfortunately unable to simply click the Install
button in the Web Part.  Before you start
to fret, however, don’t worry – there IS a solution for manually installing and uninstalling
Web Parts, and working with Windows
PowerShell, you can easily manually install or uninstall.

To
begin, you will need to extract the Web Part file folder and save it to your
hard drive. In this example, we’ll be using the Time Tracking and Management Web
Part.

Next,
go to Start > All Programs > Accessories > Windows
PowerShell. Right-click on Run as
administrator.

In PowerShell, change the directory
name to the misc folder in the Command
Prompt (cd C:UsersspinstallerDesktopSA12A.R.7.SP2010.SLmisc)

Manual
Installation:

Type the following command:
.ManualInstallation.ps1 and enter the information below:

• Enter the Web
  Application URL where you need to deploy the solution. In this example, we
  will be using server name http://foundloan.
• For the question “Do you want Automatic Feature
  Activation (Yes or No)?” enter Yes (if
  you enter no, the Web Part will not automatically activate the feature).
• Press Enter
  and wait a few minutes. Once finished, you
  will get the message, Installation Complete
  and review the result!

After installation has been
completed, you can go to SharePoint and start using your newly installed Web
Part.

Manual
Uninstall:

In PowerShell, change the directory
name to the misc folder in the Command
Prompt.

Next, type the following
command: .ManualUnInstallation.ps1 and enter the information below:

• Press Enter
  to continue.

• Press Enter
  and wait a few minutes until you get the message, Press Enter to Exit.

Your solution will now be
successfully removed.
