Error code 5 issue:Access is denied

[bartjunited]

Hi there I have 2 windows 10 laptops connected as a homegroup and are mapped to each other and a NAS drive.
When I sync to the NAS I have no issues
However when try to sync the 2 laptops no matter which way around I try or from which laptop I set off the sync I get the standard Error code 5 error as below.

Ive tried to run as Admin - no luck
Tried a regedit that was suggested - no luck

I had pick saved on tiny pic of the standard error but was not allowed to include this.

If i sync to the NAS it works fine.

Please help its driving me nuts

This is probably the normal permission issue where the user on one laptop does not have write permissions on the folder that the other laptop is sharing.
