Apps not opening after system restore

Asked By 210 points N/A Posted on -

My computer is acting real slowly so I did system restore. Now when I open some of the applications installed on my pc, it will say “application unavailable”.

Do I need to install those affected applications again? I hope there is something in the registry that I can just edit to make them working again because reinstallation is very time consuming. Please give any possible solutions to my problem. I really need it right now because I use some of those apps for work. I do not want my boss to get mad at me.

Thank you so much.

When you applied the system restore, it brought your computer to its previous state where some of your current applications were still not installed. That’s why when you tried to use one of your applications the response was application unavailable. Try restoring your computer in Safe Mode using the Last Known Good Configuration but it’s not guaranteed to work since you already restored your computer to a previous state.

  • Restart your computer. After BIOS appears and before Windows logo displays press F8. This will bring you to Windows Advanced Options Menu.
Safe Mode


  • Move your cursor up and select Last Known Good Configuration (your most recent settings that worked) and then press Enter.

After booting your computer try running any of those applications that failed to run. If the response was still application unavailable, you may need to install it again this time.

If you are experiencing slowness in your computer, defragment Windows regularly to improve data access. Update your antivirus and run a full system scan on your computer regularly to keep the system’s integrity against virus attacks. Run a weekly disk check on your hard drive using any disk utility application to keep your hard drive from having errors that usually causes unresponsive applications or prevents some applications from launching or working properly.
