#1075 Installer can't run from C:\windows\system32 on Windows x64

[Amir Szekely]

Thanks to file redirection from C:\windows\system32 to C:\windows\SysWOW64, the installer is unable to read itself and the data attached to it under Windows x64 when running from a redirected folder. Simply run any installer from C:\windows\system32 on Windows x64 to reproduce this.

The use-case where this came up was remote installer deployment with psexec -c. It copies the installer to C:\windows\system32 before running it. Furthermore, thanks to [#1076] it also hangs forever with an open message box that the guy doing the remote install can't even see.
