SELinux is preventing /usr/bin/wine-preloader from loading
/home/kiddi/.wine/drive_c/Program Files/Common
Files/InstallShield/Professional/RunTime/Objectps.dll which requires text

Detailed Description:

The /usr/bin/wine-preloader application attempted to load
/home/kiddi/.wine/drive_c/Program Files/Common
Files/InstallShield/Professional/RunTime/Objectps.dll which requires text
relocation. This is a potential security problem. Most libraries do not need
this permission. Libraries are sometimes coded incorrectly and request this
permission. The SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains how to
remove this requirement. You can configure SELinux temporarily to allow
/home/kiddi/.wine/drive_c/Program Files/Common
Files/InstallShield/Professional/RunTime/Objectps.dll to use relocation as a
workaround, until the library is fixed. Please file a bug report.

Allowing Access:

If you trust /home/kiddi/.wine/drive_c/Program Files/Common
Files/InstallShield/Professional/RunTime/Objectps.dll to run correctly, you can
change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/home/kiddi/.wine/drive_c/Program Files/Common
Files/InstallShield/Professional/RunTime/Objectps.dll'" You must also change the
default file context files on the system in order to preserve them even on a
full relabel. "semanage fcontext -a -t textrel_shlib_t

Fix Command:

chcon -t textrel_shlib_t '/home/kiddi/.wine/drive_c/Program Files/Common
