Please remove the previous version from the device and install new version again
Ok so I have App Center. Deployed them and spread out the Redemtion codes for Apps. Then the new Manage VPP option came along.
Well we had a sales guy quit. I did a remote wipe. The device came in. I setup the new guys loging for everything etc. etc. I no longer saw an app that was previously on the device due to the wipe. However I gave this new App deployment option a try. It works well other than this device that I redeployed. It states the below when he tried to install.
"The previous version of the App was installed without MDM and so it cannot be updated via MDM.Please remove the previous version from the device and install new version again"
Problem is the old app is nowhere to be found on the device. Any suggestions? I really don't want to have to restore the device to default and reset everything up. Device is in another state.
