Hi everyone!
Have installed MDT5pp from server and running the program well for about 8
month, but suddenly find some big problem and solved it with uninstall MDT5
on the workstation, followed by reinstall it again, using same setup-file as
before. But finding that i can´t reinstall it again, but facing this
message: Error The following serial number you entered is not valid: -
Please try again Why?? I have entered the right serial number on server. Any
help would be appreciated.
