Re-installation failed due to different application signatures - Released app

My app is released and being used. I moved the development folder from my E: drive to C: drive and updated the various links to the libraries. Works great, but when I try and push it to the phone that has the previous version I get the above error.

As this is released I don't want the users to have to uninstall the app. There is a database where they have been storing info, and even though they are supposed all backup, someone will forget.

If I copy the APK to the phone, and then install it, it over writes the existing version without notice.

I seem to remember something like this when my workspace got corrupted and I seem to remember having to rename or delete a file or something.

the debug.keystore in the .android is the same file with a date from several months ago, so I don't think that is the problem.

Output end of the two APKs verifying jarsigner.exe, these are the only lines that are different that I can see.

Typically this only occurs if you changed the key you signed with OR you changed the values of android:sharedUserId, android:sharedUserLabel or application process in the AndroidManifest.xml.

If you did change any of those you are out of luck.
