Hi Betty,
The ccCommon file is indeed related to the Microsoft Installer, which all applications use to install applications in Windows. It appears that the best course of action here is to make sure that Norton internet Security is installed correctly. Therefore, I am going to give you instructions on how to completely remove Norton Internet Security and perform a fresh, clean installation.
The first thing to do is to make sure that you have all of the Microsoft updates applied to your computer. Please run the Windows Update feature until it informs you that you have all of the latest patches applied.
1. Click on the following link to download and install the Norton Removal Tool, which will completely remove any Norton products you have installed on your computer. Please follow the instructions carefully.
Norton Removal Tool and Instructions
After you run this tool and are prompted to restart your computer, please repeat the process 1-2 more times to make sure that it has completely removed Norton products from your computer.
2. Make sure that your Internet connection is functioning properly, and then insert the CD and reinstall Norton Internet Security 2008. Towards the end of the installation, LiveUpdate will automatically run.
3. When the installation is complete, manually run LiveUpdate again in case there are further updates that are available. You can manually run LiveUpdate by doing the following:
Click "Start,"->"All Programs,"->"Norton Internet Security,"-> and then choose "Norton Internet Security."
4. In the left side of the window, click on "Run LiveUpdate."
5. After the LiveUpdate process has completed successfully, click the "OK" button to exit out of the LiveUpdate window. You should now be back in the main Norton Internet Security window.
6. The next step is to check the Scan settings. In the left pane of the window, click on "Options," and then choose "Norton Internet Security."
7. In the left pane of that window, click on "Real-Time protection," and then "Auto Protect." In the bottom of this window click on the "Page Defaults" button.
8. In the left pane, click "Manual Scanning." In the bottom of the window click on "Page Defaults" button, and then click "OK."
9. You should now see the main Norton internet Security window. In the left pane click "Scan Now."
After the scan has completed,(it could take some time depending on how many files are on your system) close the Norton Internet Security window and then try launching one of the applications that was previously bringing up the ccCommon dialog, and hopefully this time the application will launch correctly. If you still experience the same behavior after completeing the reinstall process, then the problem is related to Windows itself, and I would suggest that you contact Microsoft for a resolution.
Thank you,
Mike
