Question

iPhone: Application Install Fails With "Invalid Signer" Error

Answer 1

+1 A:

(Ignore: I misread the question and didn't notice he had dozens of installs already so my advice does not apply)

If you have just the standard developers account, you can only install on up to five phones before the certificate becomes invalid for further installs. If you've already installed it on five phones that is most likely the problem.

Tell Buzz some random guy on the internet said, "Hi!"

Where do you get that number (five) from? The Developer Account allows you to install Adhoc Distributed applictions on up to 100 registered devices.

I pretty sure it used to restrict to just 5. It was the big difference between the standard and enterprise accounts. I haven't looked at it recently however.

Answer 2

+1 A:

We can install it on 100 iphone with our account. We have about 40 iphones in this provisioning profile and it works on 38 of them. Any other ideas?

I'll tell Buzz that you say hi and if you can help us we'll get you a moon rock!

Yeah I just noticed while editing that you had over a dozen installs. What do the two phones that don't work have in common e.g. model, system version, installed apps etc.

You should not use the answers section for clarifications or additions to your question. Use the comment section instead and/or edit the original question.

Answer 3

+1 A:

A couple of things to try:

Renew the profile at the Developer's portal. It may have expired or become corrupt.
Create a new provisioning profile

+1 I had an issue like this and a new provisioning profile helped fix it

Answer 4

A:

Does the mobileprovision file show up on the device after sync? You should see it in

Settings->General->Profiles

If it doesn't then that would be the problem. Check once again that the UDID is correct - same UDID on iTunes and in the developer portal. Try syncing iTunes with the mobileprovision without trying to install the app. If it still doesn't get installed then CHECK THE UDID. If it is getting installed on all other devices, UDID is most likely the issue.

The provisioning file is getting installed

Scot 2010-02-27 05:56:29

UDID is 100% correct.

Scot 2010-02-27 06:01:06

Ok. Do you have an entitlements file in your app (a .plist with just one checkbox). Make sure that for an adhoc build, the check mark is unchecked. Also what is the OS version on the device and the SDK version with which you are compiling the app?

lostInTransit 2010-02-27 06:38:27

I have it running on my iphone and a few dozen others with a valid entitlements file (unchecked). Today I just created a new provisioning file with just their ID's and a new name. I sent it to them to see if that might work. They have the most up to date itunes software and iphone software. We checked. x-code is ver 3.1.4. Any other ideas? I'll let you know what happens when they try to install the build with the new provisioning file (new name and just with their ID's). THANKS!!!

Scot 2010-02-27 17:09:12

Probably not important but the latest Xcode version is 3.2.1. You could try updating on the off chance that fixes something.

TechZen 2010-02-27 20:37:26

Hey Scot, got this working?

Answer 5

A:

Does the answer to this question help you at all?

http://stackoverflow.com/questions/1857414/signer-not-valid-error

Put the signing at the Target level, not the Project level

I'm personally not sure what that means but it worked in that case

Answer 6

+2 A:

I had a fix that seemed to work for one user who was having troubles:

remove all offending profiles and apps
restart
add back provisioning profile FIRST
sync device
now add app resource
sync again to get app on device

the offending machine was a windows box... dunno if that makes a difference.

If someone else gets this issue - try this and let us know if this is the actual fix or workaround! This goblin has rarely been seen and solved with the same steps.

this was my reference for the fix idea:
