"You do not have the permissions necessary to install this application"

I have been working with Google App Engine in conjecture with Google Apps for your domain, and their have been...quirks. The latest being that I recently added an application identifier that was a randomized series of letters and numbers (to avoid the dreaded "Sorry 'omgponies' is not available" message in the app creation process.

The App ID I made (now disabled and scheduled for deletion) "806df7ef93" created successfully, and I uploaded my app content just fine, but when i went to https://www.google.com/a/cpanel/[domain.com]/SelectServices and entered the correct App ID, I got the message:

"You do not have the permissions necessary to install this application"

I was a bit confused as I was logged in with an account that was an "Owner" of the application, but I happened upon a post by kernixski that suggested that this problem would occur if the App ID ended in a number.

Obviously there are other reasons for this error to manifest, and changing your App ID to not end in a number will probably not affect those cases. However, after choosing a new ID that doesn't end with a number, this process worked perfectly. Now, if I could only use my native Google Apps account in AppEngine without a Gmail.com proxy account, things would really be looking up.
