iPhone app could not be installed at this time

Question

i was trying to install my iphone application from testflight. it installs perfectly on few devices but in some after installing about 80 percent it gives an error \"Unable to d

Answer 1

Most common issues that cause this are (from testflight's website):

• Device storage is full
• The provisioning profile is a developer provisioning profile
• The ad hoc distribution provisioning profile is corrupted and the device is having an issue with it.
• The device was restored from a backup and is causing a conflict for over-the-air distribution
• There was a network timeout
• Architecture settings of the build and the device are incompatible ( can sometimes happen -when "Build Active Architecture Only" is on when building).
• Not Using Mobile Safari.

for me it turned out that my client's ipad was running iOS 4.2.2 and my project supports 5.0+.
