MSIX Fix-up Advice for Access Denied

Hi all.  I have an app that tries to write to a log file in a folder on the root of C:\, and is getting access denied errors in Process Monitor. 

The folder (C:\VIS), when captured, resolves to [{AppVPackageDrive}]\VIS in the package (note that it tries to write to C:\VIS though and not this folder in the VFS).  The log file also has an upper-case .LOG extension (I think the Regex patterns are a bit finicky with case).

I've tried a couple of FileRedirection fix-ups, but neither seems to make a difference - does anything look wrong here?  Thanks!
