Repair failure after MagCore.dll not found

got error message “The program can’t start because MagCore.dll is missing from your computer. Try reinstalling the program to fix this problem.” Downloaded setup.msi and ran repair, got message:“The file “MailClientMainFile” cannot be installed because the file cannot be found in cabinet file “”. This could indicate a network error, an error reading from the CD-ROM or a problem with this package.” To check setup.msi has size 13.6MB. Search in Explorer does not find, faulty download?

Version is 5.0.18025.0


Problem with MagCore.dll seems to be caused by another program from ArcSoft company because eM Cleint does not use this .dll file.…

than second problem looks like faulty download, please try downloading it again.
