Generally, the trial period of the skyline software is one month. For example, the trial period of the currently applied skyline software is from 2010.4.28 to 2010.5.27.
So the system time of my computer must be guaranteed to run the software within this period of time.
If you run the skyline software beyond this time range, an error message is displayed. Once an error is reported, the software cannot run again even during the trial period of the application.
The final solution to the skyline trial software expiration problem is:
Delete the Registry HKEY_CURRENT_USER
-> Software-> Microsoft-> Windows-> CurrentVersion-> winuploader
Then make sure that the system time of the computer is within the trial period, and you can use the software again.
The trial software of Skyline is bound to the machine code. If the hardware environment of your computer changes, the trial software you apply for will no longer be available.
