I believe the original issue was because so many records were being updated at once.
In that case, I recommend just doing one action at a time, by unchecking the other 2. For example, uncheck the "records to be updated" and "removed", and leave the "records to be added" option checked. Let WINDOW do that update, and then start the update again, but just check the "records to be updated" option, etc.
However, this second issue does sound like a permissions problem, if the message is "Can't find the Optics standards file".
I assume this message is coming from Optics (not WINDOW).
Optics uses a file called "UseOptions.txt" for all the settings. That file is found here
C:\Program Files (x86)\LBNL\Optics6
Here are the contents of that file, where the various settings are. The path for the Standards file is
C:\Program Files (x86)\LBNL\LBNL Shared\Standards\
Shown here
So the first thing to do is to verify that the Standards folder is there, and then to verify that the correct standard is there, which in this case is
W5_NFRC_2003.std
And also, verify that you have permission to access the Program Files (x86) folder, which is one of the reasons to run Optics and WINDOW and Administrator.
