I suggest that you troubleshoot first, instead of a hard reset. Factory reset is within settings.
If any google app won't download nor install, it's probably because your google services are not updated or is corrupted. Try the next steps before factory reset.
1. Go to settings, scroll down to app.
2. From here search for PlayStore and tap it.
3. Tap Clear Cache and Clear data.
4. Go Back.
5. Search now for Google services, this one is not under the download tab, which you can notice at the top of the screen, instead got to All and scroll down until you find it.
6. Tap Clear Cache and Clear data if available.
7. Reboot phone or tablet.
Most of the time this procedure do work, some people also opt to remove the google account and sign in after the reboot.
After the boot, open the PlayStore, accept the agreement and try to download anything from the PlayStore that is compatible with your tablet. Also, just to be sure, go to settings, security, look for Unknown Sources and enable it. This feature allow you to install any apk file that is not from the PlayStore.

Make sure by going to the Application Manager under Settings and verify that you haven't just lost the icon on some page. The playstore is normally loaded as part of the operating system for your device. There are places where you can download an installable file for the playstore, but some devices will not allow installation of downloaded .apk files, or require you to turn off a setting that prohibits installing downloaded files. Without knowing the mfr and model number of your device, who knows what you would have to do to get this app reinstalled if you truly have somehow deleted it.

You mean App Store? Maybe because your password has been modified or the phone got reset on passwords and you need to log in again. Try that first. Otherwise you need check settings on App Store. Good luck.

That's because the Hipstreet Flare tablet does not support the Google Play Store. Several of the cheaper tablets, and many of the proprietary ones (such as Amazon Kindle Fire) don't. You can manually download the APK files, upload them to the tablet, and install them that way, but you can't actually install apps directly from the store to the tablet.
