Abnormal error running ExpressCache

I think I’ve finally found the cause of the malfunction of the software ExpressCache!!
In practice, I had an entry in the registry (probably due to a bug in the upgrade of Adobe Flash Player) that prevented the proper execution of ActiveX components.
To resolve this problem, open the Registry Editor (regedit) and search for the key HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Internet Settings \ Zones \ and there you will see there du a square (or some other symbol “abnormal”) and then correct the subkeys 0, 1, 2, 3, 4. Simply delete the key with the square or the symbol that has been found and the operation of the ActiveX again be correct!
As soon as I clicked on the item ExpressCache the software is up and running and I was finally allowed to activate it!
