I have run to the same problems aswell, and the 1365VidChng.exe doesn't work for me ethier. Is it because I'm testing on VMware as opposed to a real machine. I know that installing in VMware, the only Sync rate avaliable is 1. Is it possible to incorperate a method that can determine the best settings and impliment them in RunOnceEx at first logon? I've tried many things including... REG ADD %KEY%\000 /VE /D "Setting Screen Resolution" /f REG ADD %KEY%\000 /V 1 /D "1365VidChng.exe 800x600x32@1 -q" /f REG ADD %KEY%\000 /VE /D "Setting Screen Resolution" /f REG ADD %KEY%\000 /V 1 /D "%systemdrive%\Windows\System32\1365VidChng.exe 800x600x32@1 -q" /f REG ADD %KEY%\000 /VE /D "Setting Screen Resolution" /f REG ADD %KEY%\000 /V 1 /D "1365VidChng.exe 800x600x32@1 -q" /f REG ADD %KEY%\000 /V 2 /D "1365VidChng.exe 1024x768x32@60 -q" /f The last one is my attempt to have multiple settings. If the secound resolution is possible then it will be activated, however if not the previous would work. I've been trying all types of things, but have unable to get it to work. It does work if I run it all by itself once I get to the windows desktop in a CMD file. Any help
