You can try the registry fix from Winhelponline.com, however, I can't speak for a 3rd party site since I haven't used the solution before. You would have to try it at your own risk.
The following are steps I usually suggest for Windows Installer Errors troubleshooting. Some of them you may have tried before.
A digital Office product key is transmitted to your PC, so you won't need or receive a printed product key. You activate Office by selecting the Activate Office button. Be sure to activate Office as soon possible. The offer will expire 180 days after you activate Windows. Get help with activating an Office purchase or free offer on a new PC.
You may follow the steps from the below link: How to troubleshoot problems that may occur when you install, uninstall, or upgrade a program on a Windows-based computer: http://support.microsoft.com/kb/2438651
Step 1: Check the Windows Installer Service.
1. Click Start Orb, in the start search box, type Services and press Enter.
2. Scroll down and find the Windows Installer. Double-click “Windows Installer” in the Services list.
3. On the General tab, make sure the service is started under “Service status”.
4. If the service is not already running, under Service status, click Start, and then click OK.
Step 2: Unregister and re-register the Windows Installer
1. Click Start Orb, in the start search box, type MSIEXEC /UNREGISTER, and then click OK .
2. Click Start Orb, in the start search box, type MSIEXEC /REGSERVER, and then click OK . After you run this command, the operation is complete.
3. Now, try your installation again.
Step 3: Clean any pending installations
Check the following registry key and clean any entries in the key that you find:
Go to the Start Orb, type in Regedit and select enter.
If you get the User Account Control dialog box that states, Do you want to allow the following program to make changes to the is computer?, Click yes.
Modifying REGISTRY settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of REGISTRY settings can be solved. Modifications of these settings are at your own risk.
Scroll to: HKEY_LOCAL_MACHINE SoftwareMicrosoftWindowsCurrentVersionInstallerInProgress
Check the following registry key and clean any entries in the key that you find:
HKEY_LOCAL_MACHINE SystemCurrentControlSetControlSession ManagerPendingFileRenameOperations
Step 4: Check the permissions
Verify the System has Full Control on the following keys:
HKEY_LOCAL_MACHINE SoftwareMicrosoftWindowsCurrentVersionInstaller
Next, restart your computer and try again.
If still having problems, then create a new Administrator User account and see if the problem could be a corrupt user account.
Please reply back and let us know if this helps with your Windows Installer Error.

Command To Re Register Windows Installer
M.A.R.5 Answers
This one worked for me, just combined the commands from the other answers found here. Note: you have to use the -Allusers option with the Get-AppxPackage command since it is not installed anymore under your current user account:
Here is the MS Store link to the Windows Calculator.
Note: This will only work if you have the Windows Store app installed.
To reinstall an individual app use PowerShell and run it in admin mode.Screenshots:
Next get the full name of all apps, e.g. Windows Calculator paste this snippet in PowerShell and hit enter:
get-appxpackage -allusers Select Name, PackageFullName
For single full name of the desired app name, e.g. Windows Calculator paste this snippet in PowerShell and hit enter:
Get-AppxPackage *windowscalculator*
Now copy the full name that looks like this: Microsoft.WindowsCalculator_10.1601.49020.0_x64__8wekyb3d8bbwe
Finally the we are going to install that app again with this snippet:
Add-AppxPackage -register 'C:Program FilesWindowsAppsMicrosoft.WindowsAlarms_10.1603.12020.0_x64__8wekyb3d8bbweappxmanifest.xml' -DisableDevelopmentMode
Re-installed app is available without restart of the PC!
N.b: To remove individual apps use this code:Get-AppxPackage *alarms* Remove-AppxPackage
A list of all apps when removing is (Here)
Stephen RauchUnregister And Reregister Windows Installer
Try Get-AppxPackage *windowscalculator* Add-AppxPackage
or the following to install all default apps:Get-AppxPackage -AllUsers Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppXManifest.xml”}
Just install it from the Windows Store if you have that installed.Windows Calculator https://www.microsoft.com/store/apps/9wzdncrfhvn5
