Hello dsdsfd,

I understand you are having issues with your adCenter Desktop. To get you the best answer possible i will need your assistance by answering a couple questions.

1. Is the first time you are installing the adCenter Desktop?
2. Have it ever worked for you?
3. Have you tried to uninstall adCenter Desktop?
4. Have you Uninstalled the SQL Server in Control Panel > Add and Remove Programs?

Please try the Following.

1. Uninstall the adCenter desktop.
2. Uninstall the SQL Server
3. Delete localstore:

Here are the correct steps to reinstall the Desktop tool:

1. Close the adCenter desktop Tool
2. Open the "RUN" bar from the Start Menu. If you do not have the "Run" option on their menu, there is a 'hot-key' command they can use (WINKEY+R).
3. In the "Run" bar, type in one of these 2 strings depending your operating system:
   Windows Vista: c:\Users\%username%\AppData\Local\Apps\
   Windows XP: C:\Documents and Settings\%username%\Local Settings\Apps\
4. Once the directory loads, rename the "2.0" folder.
   example: 2.0____old

Reload the Desktop Tool. When the you launch the desktop tool, this will rebuild all of thelocal files and you will also have to download your entire account, this is similar to reformatting.

There is also the Localstores files that you can also remove, here is the locations for XP and Vista:

1. Windows XP: C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft
   Windows Vista: C:\Users\%username%\AppData\Local\Microsoft\MAF
2. Once the directory loads, rename the "Localstore" folder.
   example: Localstore____old"

Final Step: Re install the adCenter Desktop. By doing this it will re-install everything.

Hope this helps
