Fix for read-only files when copied from CD

[Brutal Sponge]

I'm not sure if this has been discussed or suggested before. I did a quick search and didn't turn up anything.

I've found what you could call a solution to the problem of files being read-only when copied off the CD. Instead of using the commandline to set the file attributes (which i had problems with), you can use WinRAR's Unrar.exe cmdline utility.

I'll provide an example. This is for the RunOnceEx method, but could probably be adapted for the batch file method.

First, get WinRAR installed then navigate to its folder. Copy the 'Unrar.exe' file to '$OEM$\$$\System32' - this will ensure that you can call it from anywhere during the setup.

In this example I'll use mIRC. Create a RAR file (not zip!) in your 'install' folder called 'mirc.rar'.

Next, open your RunOnceEx.cmd file and add:

REG ADD %KEY%\014 /VE /D "mIRC" /f

REG ADD %KEY%\014 /V 1 /D "unrar.exe x %systemdrive%\install\mirc C:\PROGRA~1" /f

This will unrar mirc.rar to 'C:\Program Files\mIRC'. You can change where stuff is extracted to by simply altering 'C:\PROGRA~1'.

You could also use different commandline switches if required.

I've tested this and it works.

Anyway, hope this helps!

Just creat an sfx and call it with /s for silent...

True. Never thought of that for some reason.

Or even better creat a sfx from 7zip wich compress much more.

But even with the silent switches you get a window telling you its extracting...

For winRAR sfx's Be sure to set the modes to overwrite always and silent and put the extract to path in there as well. Then all you got to do is "somefile.exe". No switches or paths needed.
