Still can't open AC!

[JGAN]

semi-trolling here... lol

Run cmd
cd \Program Files\AssaultCube_1.1.0.3\bin_win32\
cacls /g <YourUserName>:f ac_client.exe
cacls /g everyone:f ac_client.exe

If it is a permission problem, that will give it full control and should run.

knowing what "cmd," "cd," "cacls," "rm," "sudo," and about 50 more probably will help you a good deal in coding...

cmd-command prompt
cd-goto/find directory
cacls-yes/no
rm-remove
sudo-root
mkdir-create directory
ftp-file transfer protocol
bat-batch file
echo-repeat text
print-repeat text (python)
#!/bin/sh-shell script for linux and stuff
exe-executable
