On Windows 10 64 Bit Scribus 1.5.4 does not start or run. The reason for this is that the files MSVCP140.dll and VCRuntime140.dll are missing in the portable app package. Either include these files in the package or tell users that they need to down load them from the Microsoft Site and place them in directory X:\PortableApps\ScribusPortableTest\App\Scribus where X is the drive on which the user has stored Scribus Portable Test.
Thanks in advance

I copied Hermes100's post from the announcement so it is tracked by the bug tracker.
