UPDATE [10/12/19]: see this post for an important update regarding private store distribution improvements.
I’ve received questions from a small number of users that have Windows App store disabled by their IT departments. Microsoft fully supports private store app distribution for approved by IT apps. If you work in one of these locked down organizations, please encourage your IT to try these steps: https://docs.microsoft.com/en-us/microsoft-store/distribute-apps-from-your-private-store. Windows Apps store is by far much more secure way to distribute and seamlessly update modern apps. I’m posting this because someone just now chimed in and said that his IT department locked the app store distribution, but would allow him to run an exe. This is such backwards thinking. App store apps at the time of publishing are checked by Microsoft staff, scanned for viruses and are digitally signed when they pass pretty stringent security, regulatory and quality criteria. We need to collectively do some IT educating here – if they lock down the app store access, they definitely should invest in the setup of the private store for critical to business users app like the XLStyles Tool. Now, I don’t have the environment to test this out, so if you went through the steps in your org, please share your experience. You are getting XLStyles Tool for free, so please spend couple of minutes for the benefit of the user community to share your experience and important tips if you successfully setup you private store.
