Microsoft has had to stop new apps being published to the Windows Phone Marketplace, due to a digital certificate problem.
The problem hit during the rollout of the new described the problem as a "hiccup" that had to do with the store's back-end infrastructure being changed over., a repository for developer tools. At some point, an issue with digital certificates arose that stopped some phones from installing recently-published apps. Marketplace chief Todd Brix
"We've already identified the problem and are working to resolve it and resume certifying and publishing apps as quickly as possible," Brix said in a blog post.
The problem only seems to affect handsets that have been upgraded to Windows Phone 7.5, rather than those sold with that version of the operating system already installed.
"We estimate the issue also affects only a small percentage of the 100,000-plus apps in Marketplace," Microsoft's Mazhar Mohammed wrote in a blog post on Tuesday. "Among the more popular ones affected are the New York Times, WhatsApp, and Translator from Bing — all of which recently issued new updates."
The most awkward aspect of this situation is that affected users get presented with a Windows Phone message that reads: "We're having trouble installing this app. Tap and hold the item, then tap Retry. If you're trying to update an existing app, and the problem continues, you might need to uninstall the app then install it again."
Brix urged users not to uninstall the app, despite what the message says, because it may be impossible to re-download the app until Microsoft has deployed its fix.
"If you've already uninstalled the application or deleted from your download queue, please wait until we can provide further guidance," one piece of official Microsoft advice read.
