Hi PetekeMojela,
Thank you for posting in Microsoft community!
I am sorry to hear that you have issue with the apps to download.
Method 1: Perform a clean boot and try to install the apps
Putting your system in clean boot state helps in identifying if any third party applications or startup items are causing the issue.
Clean Boot
Step 1:
a) Press the ‘Windows + R’ key on the keyboard.
b) In the ‘Run’ windows type ’MSCONFIG’ and click ‘Ok’.
c) Click the ‘Boot’ tab and uncheck ‘Safe Boot’ option.
d) On the ‘General’ tab, click to select the option ‘Selective startup’, and then click to clear the option Load startup items check box.
e) On the ‘Services’ tab, click to select the ‘Hide all Microsoft services’ check box, and then click ‘Disable all’.
f) On the ‘StartUp’ tab, click ‘Open Task Manager’. In the Task Manager window under startup tab, right click on each startup item which are enabled and select
‘Disable’.
g) Click ‘OK’, and then click Restart.
Step 2: Enable half of the services
a. Follow steps 1a and 1b to start the System Configuration utility.
b. Click the Services tab, and then click to select the Hide all Microsoft services check box.
c. Click to select half of the check boxes in the Service list.
d. Click OK, and then click Restart.
Step 3: Determine whether the problem returns
If the problem still occurs, repeat step 1 and step 2. In step 2, click to clear half of the check boxes that you originally selected in the Service list.
If the problem does not occur, repeat step 1 and step 2. In step 2, select only half of the remaining check boxes that are cleared in the Service list. Repeat these
steps until you have selected all the check boxes.
If only one service is selected in the Service list, and you still experience the problem, the selected service causes the problem. Go to step 6. If no service
causes this problem, go to step 4.
Step 4: Enable half of the Startup items
If no startup item causes this problem, a Microsoft service most likely causes the problem. To determine which Microsoft service may be causing the problem, repeat
step 1 and step 2 without selecting the Hide all Microsoft services check box in either step.
Step 5: Determine whether the problem returns
If the problem still occurs, repeat step 1 and step 4. In step 4, click to clear half of the check boxes that you originally selected in the Startup Item list.
If the problem does not occur, repeat step 1 and step 4. In step 4, select only half of the remaining check boxes that are cleared in the Startup Item list. Repeat
these steps until you have selected all the check boxes.
If only one startup item is selected in the Startup Item list, and you still experience the problem, the startup item that is selected in the list is the service
that is causing the problem. Go to step 6.
If no startup item causes this problem, a Microsoft service most likely causes the problem. To determine which Microsoft service may be causing the problem, repeat
step 1 and step 2 without selecting the Hide all Microsoft services check box in either step.
Step 6: Resolve the problem
After you determine the startup item or the service that causes the problem, contact the program manufacturer to determine whether the problem can be resolved.
Or, run the System Configuration utility, and then click to clear the check box for the problem item.
Step 7:
Note: After you have finished troubleshooting, follow these steps to boot to normal startup.
a) Press the ‘Windows + R’ key on the keyboard.
b) In the ‘Run’ windows type ’MSCONFIG’ and click ‘Ok’.
c) On the ‘General’ tab, click the ‘Normal Startup’ option, and then click ‘OK’.
d) When you are prompted to restart the computer, click ‘Restart’.
Method 2: Network and Internet troubleshooter & TCP IP
Step 1: Let’s run the Network and Internet troubleshooter and check if that helps.
Follow these steps to run the troubleshooter.
a) Move the mouse to the bottom left corner of the screen and right-click on the ‘Start’ icon and select ‘Control Panel’.
b) In the search box, type ‘Troubleshooter’, and then click ‘Troubleshooting’.
c) Under ‘Network and Internet’, click ‘Internet Connections’.
Step 2: If the issue persists then I would suggest you to reset TCP/IP and check if it helps.
a. Press “Windows Key + Q” to open Charms Bar.
b. Type “cmd” without quotes in the search box.
c. On the left pane, right click on the “cmd” option and select “Run as Administrator”.
b) In the command prompt, copy and paste (or type) the following command and then press ENTER:
netsh int ip reset c:\resetlog.txt
Note: If you do not want to specify a directory path for the log file, use the following command:
netsh int ip reset resetlog.txt
c) Reboot the computer and check with the issue.
