Had to install new copy of xlights 2017.30 onto a new laptop, due to old one dying. It appears to install fine, but at the end i get the following errors: Unable to create directory! Backup Failed. Close that, then this comes up : Directory 'C:\Program Files(X86)\xlights\backup\2017-10-25-114456_OnStart' could'nt be created. (error 5: access is denied). Have tried the install process numerous times with the same results except for the six numbers before OnStart . Any help wold be gratefully appreciated.
