error code 5 error

[Ubin]

Good day: I recently downloaded and installed Free File Sync ( which i used without issue several years ago).
I am running into a problem on a windows 7 machine, i am running this from and admin level account.
When i run the compare tab, just above the directories it states:
Waiting while directory is locked: "C:\Users\main\sync.ffs_lock"

then after a period of time i get a warning screen that states:
Cannot set directory lock for C:\Users\main\

Cannot write file C:\Users\main\sync.ffs_lock

Error code 5: Access denied (Create File)

The dialog line above the directories changes to:
C:\\Users\main\Del.sync.ffs_lock

What is happening and how can it be resolved.

Thank you

I am given the option to ignore the error, but i am not sure how that will affect the backup.

Try to enable ffs to copy locked files options in settings.

The Backup will copy the file in it's last property state.

Can anyone else confirm?

So i should change the value to false under <LockDirectoriesDuringSync Enabled="true"/>
?
Then how does that affect my backups if at all?

i changes that value and that error dissappeared, now i get the following when i try to start the sync:

Cannot set directory lock for "G:\Asus Backup Main".

Cannot write file "G:\Asus Backup Main\sync.ffs_lock".

Error Code 2: The system cannot find the file specified. (CreateFile)
