Microsoft has fixed a bug that was affecting its Windows Phone store which prevented users from installing various apps.

UK based technology site TechRadar found the fault and the affected apps included New York Times, WhatsApp and Translator from Bing.

Microsoft temporarily stopped new apps from being entered into the store while it investigated the bug, according to a report by the Telegraph.

According to Todd Brix, writing on the Windows Phone Developer blog, the problem was occurring on older handsets, which had not been upgraded to Windows Phone 7.5.

The bug reportedly prevented Windows Phone 7.5 users from downloading new apps as they also encountered an error message.

Microsoft estimated the issue affected a small percentage of the 100,000-plus apps.

Earlier in August 2012, Microsoft launched the Windows Phone Dev Center, providing a venue where developers can build, publish and manage apps for Windows Phone 7.5 and the upcoming Windows Phone 8.

The company is preparing to release its updated mobile operating system and is looking for developer support to compete with Google’s Android, Apple’s iOS, and RIM’s BlackBerry OS.
