Have the vendor of the application, whether it is a valid Windows Installer package./ I suspect the installer can not download the whole package, because the progress bar is not completely filled. It would be nice if there was the possibility of an alternative download. The 'mono-android-4.4.54.208556545.msi' has a size of 167.621.080 Bytes (Size on disk = 167.624.704 Bytes). Thanks for help.
