Try not only to make sure you've spelled things correctly, but also to put the Install directory in the correct location! D:\XPCD\$OEM$\$1\Install This will copy it ito %SystemDrive% during setup as per your RunOnceEx.cmd. P.S In the script you've provided there appears to be missing double quotes on your n-Lite.exe line. Thanks dear for your fast reply I checked, the Spells it was correct I just put Install folder in $1 & it work. Now Adobe installing wizard open (means it like manual install ...next- next & finish), it’s not installing silently....? Any help is welcome Thanks & Regards
