Question about saving files in a Windows Application

I'm using a 32 bit application in Windows 10 Pro in Parallels 12 in a MacBook Pro running High Sierra 10.13.13
I cannot save files anymore with the 32 bit application.
So I purchased NTFS for Mac to gain read/write access to a external hard drive I use for backups.
So while I'm in the windows 32 bit application I cannot save files to the external hard drive.
Does anyone have any tips?
I've run out of areas to troubleshoot other than upgrading the 32 bit windows application - the only reason I use Windows
