Frequently asked questions

  • Is there any functional difference between .NET 3.5 and .NET 4.5 versions?

    No, both versions are identical. The different versions of .NET Framework were simply built in order to avoid the additional installation of a specific version.

  • Why does the list of errors in the Event Log section change from run to run?

    The list of errors in the Event Log section is a subset of Windows Event Log items, which only contain errors and warnings that have been logged during last 24 hours. Older items are removed as time passes and fresh items replace them.
