This error usually experienced when we just re-install our windows 8 or windows 8.1, it happens when we want to download application from windows store.
Why this error happens?
i don't know the exact answer, but i think this error occur because windows stored our application information online. so, when we download application, windows saves this information (which app we download) and when we re-install windows we lost those apps but windows doesn't care about it and still think that we still have the apps so the windows doesn't erase the information about our application. So, windows think that we download the application twice.
What we can do?
i think we should edit our registry
just follow this instruction
1. Open Notepad
2. Copy the following line to Notepad
sc config wuauserv start= auto3. Save with repair.bat (you can change "repair" with any text, the point is .bat). And set save as type with All Files (*.*)
sc config bits start= auto
sc config DcomLaunch start= auto
net stop wuauserv
net start wuauserv
net stop bits
net start bits
net start DcomLaunch
4. Right-Click on the file and run as administrator, enter the password (if necessary)
5. The command-prompt will appear, wait for the process. the program will close itself
6. You can download your apps again
