We spent 4 days tracking down the problem... which is SOME 64-bit installations of Windows (XP, Vista, Win7) are missing the msc80.dll and its dependent DLL's. We have not determined WHY this happens. One day, Microsoft will put their fix in a "Required" Upgrade" and all of you with this problem will see it disappear.
Once we determined the problem, we finally found a Microsoft 2.5MB .exe "fix". We updated our Installation program so when it discovers the msc80.dll is missing, it installs the Microsoft fix .exe and runs it to install the missing DLL's, then continues installing Hoster 4.22.
We are now testing this with those who had submitted a Support Ticket. If you wish to test it also before we release it, please
submit a Support Ticket and request
"I want to test the new 4.22.7 with the _ismtu.dll fix."
