Is there an installation log? Or check the Windows application event log to see if it says anything useful.
In haste here at the moment. But the blue arrows is the way Windows 10 displays NTFS compression. There are various posting on the web regarding this, but try opening Programs and running the apps directly from there. You'll probably find that they are OK and it is the shortcut that is the issue.
Again, do Google something like "Windows 10 2 arrows icon" or similar and you should find some help out there.
All the best
Thanks! I'll look into it.
