Unable to install on CentOS 6.6 "install.sh: line 38: sophos-av/install.sh: Permission denied"

Hi,

I'm trying to install Antivirus 9.10 on our CentOS 6.6 webserver, but failing miserably so far. The error that keeps re-occuring is:

install.sh: line 38: sophos-av/install.sh: Permission denied

I've unpacked the tarball in /tmp, but this is set to noexec. So I've also tried /etc/ and /opt/, but the same error appears. I'm no linux expert, so any help will be much appreciated!

I've made sure the directory and the files are all executable, but this doesn't seem to be the problem.

Line 38 of "install.sh" contains the following code:

sophos-av/install.sh "$@"

And for clarity, here's the surrounding code:

export SOPHOS_INSTALL_TMP
cd $SOPHOS_INSTALL_TMP
tar xf "$BASEDIR/sav.tar"
[ -f "$BASEDIR/uncdownload.tar" ] && tar xf "$BASEDIR/uncdownload.tar"
[ -f "$BASEDIR/talpa.tar" ] && tar xf "$BASEDIR/talpa.tar"
sophos-av/install.sh "$@"
RETCODE=$?
cd /
rm -rf $SOPHOS_INSTALL_TMP
exit $RETCODE

Help me community!
