code signing - "Can't install company app" on Windows Phone 8 -

i've developed company app windows phone 8, , have gone through recommended steps set installation. have symantec code-signing certificate, , have generated application enrollment token , signed xap, hosting in public folder on onedrive. generated xap using buildmdilxap.ps1 script, ran without errors. haven't bothered company hub app, since we're distributing single app.

the aet loads ok on phone, , asks if add workplace account. click "add", dialogue box disappears, , no error comes up. there no confirmation message, don't know if should expect one.

when load xap, message "can't install company app. there's problem company app. contact company's support person help."

the phone has been developer unlocked (which of course isn't necessary), , i've had app side-loaded , running on before. uninstalled before attempting above, however.

i'm not sure here. i've tried recompiling , re-signing xap , re-generating aet, nothing seems work.

after fruitlessly trying solve problem, found workaround need.

it turns out can post apps public app store, hide them searches, making them private doesn't have link. solves first problem, getting app published in way client can access without me needing have developer licenses each of phones.

the downside solution still have wait few days update approved, isn't greatest when you're still beta-testing , need make quick changes. however, microsoft have beta program windows phone apps. designating app beta, submission happens automatically within 2 hours, have restrict access specific microsoft accounts. latter isn't problem because number of devices using app relatively small.

this removes need corporate app store in case, , saves expense of certificate , fiddling around goes it.
