Exception dialog attached.  I manually updated TT to R24 to see if it would go away, but it does not.

I was able to solve it with the following that was found in another answer:

  1. Close TurboTax and then click here to download and install SQL Server Compact 4.0 from Microsoft's website.
  2. Open Windows Explorer and browse to the location C:\Program Data\Intuit\Common\Update Service\v4\Global.
  3. Right-click the Global.sdf file and choose Properties.
  4. Click the Security tab.
  5. In the Group or user names area, select your username and click the Edit button.
  6. In the new window, select the Allow checkbox that corresponds to Full Control, and then click OK twice to close the windows.
  7. Try updating TurboTax again.

HI, i found clearing out the directory where i was installing the forms etc helped me. If you re-install you may try to remove all files or use a new directory during the install. I also downloaded a copy of turbotax instead of using my dvd rom disk. It ran much faster. Not sure this will help in your situation but it's something to try.

Which file should be downloaded?? I see two choices: 1 is 

SSCERuntime_x64-ENU.exe

and the other is 

SSCERuntime_x86-ENU.exe

Depends on your computer.  Most likely the x64 version, unless you have an old 32-bit computer, then use the x86.

1) Close TurboTax

2) Go to Task Manager, click on the "Services" tab. Try finding "IntuitUpdateServiceV4".

3) Right click on the service and click on "Stop" to stop the updater service.

4) Once the updater service is stopped, Go to "C:\ProgramData\Intuit" path and delete the "Common" folder.

5) After deletion, restart the Updater service i.e. Go to Task Manager, click on the "Services" tab. Try finding "IntuitUpdateServiceV4" ,right click on the service and then click on "Start" option.

6) Once the Updater service is started, try opening TurboTax again.

Hello.  I tried below, but get a message that the "Global" is corrupted/unreadable when I click on the folder.  Any ideas?

I was hours on the phone with tech support, and they couldn't help me.  Thank you.  This worked.
