Method 1: Change Decimal Symbol Settings

The problem will occur when the decimal symbol isn’t set to as ‘.’ (dot). This can happen when languages and locales other than English (United States) are used, such as France (French) for example.
Follow these steps to adjust the decimal symbol setting:
  • Open the Control Panel, choose Clock, Language and Region, and then open the Region and Language settings
  • Click Formats and then click Additional Settings
  • Type . (a dot) in the Decimal Symbol field and press OK twice
  • Restart your computer
  • Note that some third-party applications can change the runtime locale of a computer and override settings from the Control Panel
Method 2: Add a Registry Key Value

Please note that serious problems may occur when modifying the registry through Registry Editor or any other method. The problems may need to be fixed by reinstalling the operating system. Microsoft is unable to guarantee that the problems can be solved. The registry should only be modified at your own risk.
  • Open the Start menu and type Regedit.exe into the Search box and press Enter
  • Find and click on the registry subkey HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\System
  • Open the edit menu, click New and then click DWORD Value
  • Type CopyFileBufferedSynchronousIo into the box and press Enter
  • Right-click on CopyFileBufferedSynchronousIo and choose Modify
  • Type 1 into the Value data box and press OK
  • Exit the Registry Editor program
Registry Edit

1. Press the Windows Key and R
2. Enter Notepad and click OK
3. Copy and paste the following lines into Notepad:

Code:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\UX]
“IsConvergedUpdateStackEnabled”=dword:00000000[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\UX\Settings]
“UxOption”=dword:00000000
4. Click on File and choose Save As
5. Change the file type to All Files and save it on the desktop as wufix.reg
6. The file should be named this because the .reg extension tells the computer to run the file through the computer registry. Run the file and accept any prompts.
