/usr/lib/transgaming_cedega//winex/bin/wine: can't exec '/home/jeremiah/Desktop/ SteamInstall.exe': error=21

What am i doing wrong here?

[frayedknot]

try running

chmod a+x /home/jeremiah/Desktop/SteamInstall.exe

first things first

[stealthredneck]

I did the chmod a+x and i still get his error 21, have you tested this?

On the cedega forums is a lot about Error 21 as this is common for the FC3 distro.

Summary
------------
To solve error 21 problems you need to:
disable prelink
turn off exec-shield
enable legacy VA_LAYOUT (2.6.9 kernel)
enable exec mount option

Check below for more information on the problems and details on fixing them.

More information
--------------------
Prelink is a new set of functionality, available in newer glibc versions
and distributions such as Fedora Core 1, designed to reduce the startup
time for applications which use dynamic libraries. The loading speed
improvements are achieved by preassigning the addresses of various dynamic
linked libraries that will be placed in memory. Thus, relocations will not
have to be performed by the dynamic loader when loading the application.
Unfortunately, more often than not, libraries are prelinked into addresses
which are incompatible with Windows programs.

Windows programs generally use a trick, similar to Prelink, to reduce the
size of the executable and improve start times. This trick
assumes, quite rightly for a Windows program, that the address 0x400000
is always available. Thus when Cedega attempts to load the Windows
executable into the starting address, and it's not available, Cedega will
fail to start the program with an error message mentioning
"stripped relocation records" and "address 0x400000 not available".

Exec-shield is a kernel level solution
(http://people.redhat.com/mingo/exec-...CE-exec-shield)
which remaps executable code to a lower memory address with the
intention of eliminating ASCII based code overflow attacks. The
new location of the executable has the potential of conflicting
with the required windows range which will result in the same error
message as with Prelink.

The solution to the problems these two new technologies create is to
disable them so that they don't affect any Cedega libraries or executable
code.

To disable automatic prelinking in the future, edit /etc/sysconfig/prelink
and set PRELINKING to no by making sure the following line is present:
PRELINKING=no
Then execute the cron job, most likely /etc/cron.daily/prelink, to
reverse the Prelink for all of your libraries or manually run:
$ prelink -ua

To disable exec-shield you can either use the boot time option
"exec-shield=0" or it may be changed, before running Cedega, by typing
either:
$ echo 0 > /proc/sys/kernel/exec-shield
or
$ sysctl -w kernel.exec-shield=0

In addition, newer Fedora Core 2, Fedora Core 3, and other 2.6.9 kernels also
require support for legacy VA layout to be enabled. This can be done
via the command:
$ echo 1 > /proc/sys/vm/legacy_va_layout
before running Cedega (this is required after every boot).
To enable legacy VA Layout at boot time, edit /etc/sysctl.conf
and add the following:
vm.legacy_va_layout = 1

Information about this can be option found on the fedora announce mailing list:
http://www.redhat.com/archives/fedor.../msg00025.html

Some distributions version of mount now run with the noexec option unless otherwise specified. Running games from a partition mounted with noexec can cause an error = 21
To fix this issue edit the /etc/fstab and modify the partition line by removing the noexec option and adding the exec switch to the mount options. For example:
change
/dev/hda1 / ext3 errors=remount-ro,no-exec,defaults 0 1
to
/dev/hda1 / ext3 errors=remount-ro,exec,defaults 0 1

If neither exec nor noexec appears in the line it is recommended that you add it.

To remount the partition run (as root):
mount -o remount /

And one important line:

I had this exact same error on Fedora Core 3, i disabled prelinking and install-sheild just like in the HOWTO

I also did this as root.

# /bin/echo 1 >/proc/sys/vm/legacy_va_layout

Don't ask me what that does it just adds something to the filesystem important thingy... i think...

P.S. you will get error=21 until you do the # /bin/echo 1 >/proc/sys/vm/legacy_va_layout thingy on Fedora Core 3......
