I get the ui container error when print previewing reports after a new ws install on windows 10.  I need to register the a4wcrinterop.dll however the challenge is that it is located on a network drive.  at a command prompt i have tried referencing the unc path and using the net user command to map a drive letter and referencing that and I can not get it to register.  Any ideas what will work   here is an example of what I have tried

C:\windows\microsoft.net\framework\v4.0.30319\regasm /register "\\servername\share\runtime\a4wcrinterop.dll"
C:\windows\microsoft.net\framework\v4.0.30319\regasm /register \\servername\share\runtime\a4wcrinterop.dll

with net use command mapping X: to \\servername\share\

C:\windows\microsoft.net\framework\v4.0.30319\regasm /register X:\runtime\a4wcrinterop.dll

on X: I changed to X:\runtime
C:\windows\microsoft.net\framework\v4.0.30319\regasm /register X:\a4wcrinterop.dll

on c i changed into \windows\microsoft.net\framework\v4.0.30319\
regasm /register X:a4wcrinterop.dll
