That sounds like my test of a backup (antique) machine in case our primary antique fails.  The install disk was version 2012,  but the database had been updated to the July version.  In my case, applying the updates before opening the company allowed the backup machine to open the files (then go back into the cupboard.)

So a re-install with the same symptom sounds like the same problem.  The updates changed the structure of the database and the error message isn't smart enough to say so.

Hi PsHiltz

Here are a few things to do:

1. Uninstall 2012 Simply Accounting once more.

2. Run your Windows Updates and make sure all your updates for Windows are completely up to date. Most important of those updates are anything to do with .Net and Framework. Those are the key words. Make sure you install ALL the important updates. Please NOTE you may have to run Windows updates numerous time to capture ALL the updates. This could take you an hour or more to complete if your updates to Windows have not been done regularly.

3. Once you have successfully done ALL of the Windows updates then shut down your computer and start it up again.

4. Reinstall 2012 Simply Accounting. Here is the link to the best place to download the file and it will be version D

The link below will update the 2012 Simply Accounting to Version E

5. Once the install is completed (making sure you are updated to Version E) restart the computer.

6. Open 2012 Simply Accounting and open the Sample Database to test the install.

Question for you which version of Windows are you using? XP, Vista, Win 7 or Win 8?

Good luck and I hope this helps.
