Hey Dave49,
I am sorry to hear that it did not work. The next steps to try, would be repairing, and then installing the Solution Center from the temp folder. To do this follow the steps below.
1. Press the Windows key, and the letter R
2. Type %temp%
3. Press Enter, or click OK
4. Open the 7z folder
5. Open the Setup folder
6. Open solutioncenter folder
7. Right click on the SolutionCenter installer
8. Click Repair
If you get the an error that the software is not installed, again right click on SolutionCenter installer and click Install.
Please let me know the outcome of the troubleshooting.
