App installation failed error

[neomodus]

Hi
I am getting "A valid provisioning profile for this executable was not found" error when I try to test install my app to my connected ipad 2 device.
My certificates and provisioning profiles appear valid and well in date and appear under xcode preferences
I have revoked and recreated these several times but get the same error
My app generates a standalone without any problems.
I am using
Mac Os Sierra 10.12.1
Livecode Indy 8.1.1
Xcode 8.0
Any help much appreciated
Thanks

Hi neomodus - silly questions follow:

1. Did you add your device's UDID on the Developer Portal?

2. Did you add your device to the provisioning profile?

3. Do you have any expired certificates in KeyChain Access? (if so zap them)

4. Do you have any duplicate provisioning profiles when you view them via Xcode-preferences-accounts? (you'll need to select your Apple ID, then select a Team Role, then click 'ViewDetails'). If you do have any duplicate profiles zap them all - make sure you only have ONE remaining valid provisioning profile for each of your apps in Xcode

5. Did you rebuild your app with a copy of the provisioning profile that included your device?

Good luck!
