Some users of Windows 8 have complained of facing various issues with apps. Either some apps fail to install or run or update or simply crash. All these versions of Windows 8 are pre-release, yet millions of people are using these versions of Windows daily. Microsoft has definitely improved the Windows Store and apps experience with each pre-release version. With the current Windows 8 Release Preview, the final pre-release, Microsoft has provided many new Windows 8 apps for connecting to Hotmail, SkyDrive, Messenger and other service-connected apps – apart from hundreds of new and updated third-party apps and games, in the Windows Store. Remember many of these are currently in App Preview. They are still collecting feedback and improving accordingly.

If when you try to run any Windows 8 App, you find that it will not work properly – maybe you get an error message App Can’t Open – you may want to run the Windows 8 App Troubleshooter.

Nevertheless, to address many of the known apps issues which may be preventing them from running properly on Windows 8, Microsoft has developed an

Troubleshoot Windows 8 Apps problems
Here are some points which can also be looked into for app issues, based on users experiences.
After running the Troubleshooter, restart your system and then check.
According to Windows 8 Release Preview System Requirements, to access the Windows Store and download and run apps, you need an active Internet connection and a screen resolution of at least 1024 x 768. So please check the resolution.
To snap apps, you need a screen resolution of at least 1366 x 768. But not to worry about this Snap app feature – if your monitor doesn’t support this resolution. It doesn’t affect in running or installing of app.
Change your Account to Local and then back to Live account from the Control Panel.
Check whether Windows is up to date with the latest updates. Also try to Sync App licenses. For this
Open the Store App,
Open Charms (
WinKey+C) ,
Select Settings>
App Updatesthen under
App Licenses, click
Sync Licenses.

If you have installed some apps in your previous Windows 8 version as Windows 8 CP then they were registered against your account. So in Release Preview a new option is provided to view the Installed apps. If you are using the same Live account to login to Release Preview then in Store, just right-click anywhere to get the Bar at top to get the option “
Your apps”.

Just click on it to list all your apps – those which have been installed now and those you had installed earlier, so try installing from there & see if it makes any difference.

These are some additional troubleshooting steps which you could try to fix your Windows 8 apps problems – apart from trying out the App Troubleshooter.
What I recommend is if you are just trying out & testing Windows 8 Release Preview, do a clean install of Windows 8 Release Preview instead of upgrading from the previous Windows version. Now give it a try and install your favorite apps from Store.
