It may happen that you try to execute a file that has the correct permissions, and the system replies with an error message like \”file or folder does not exist\” or similar.

You may get this message if you\’re trying to run an application that was link to the old C libraries on a system that does not have them. This may happen especially with Red Hat 7, since it is the first Red Hat distribution that does not include the old libc5 libraries.

First, you can verify that this truly is the cause of the problem by using the following command:
ldd [full path to command]

Then, you can fix the problem by installing the following RPM packages:

ld.so-1.9.5-13.i386.rpm
libc-5.3.12-31.i386.rpm
