Problems with permissions on PXI after 8.6.1 update

[CoastalMaineBird]

My host program communicates (via TCP) to my RT program on PXI box.It can update itself by a) telling RT program to terminate, B) FTP sending a new version (using Internet toolkit), and C) rebooting the RT (using RTSystemReplication library).This worked fine on LV 8.2.Today I updated everything to 8.6.1 and NIDAQmx 8.9.The update would not work: the host got Error 15550 - could not open file (550).Using other FTP tools, I found that I could not delete the RTEXE file on the PXI from there, either. Even another computer wouldn't do it - error 550.Permissions on the containing folder are 755 - owner and group may NOT write.I can rename the folder it's in, but I may not delete that folder, or the file itself.Again, I see the same situation from other FTP tools.I see no method in MAX to change the settings for FTP purposes...What do I do?

FWIW, NI Tech Support has responded with a reference to this doc:

http://digital.ni.com/public.nsf/allkb/6EDCBF0F0498814F86256B570080DD20?OpenDocument

The doc basically says to rename the file before you delete it.  That works, for some reason.
