Thanks for the image. I was after what IS was trying to launch.
If you look under the Inner Space configuration option, what are the settings of the Use 64-bit Inner Space Uplink and Use same-bit game clients. Seeing as it is launching WoW-64.exe, both those options should have a red dot. If you need to change them, exit and relaunch Inner Space.
Have you tested whether running the 32bit WoW works? What about the dx9 game profile?
You could just delete the WoW-64.exe and then re-patch. it should redownload just the exe, although if it is a dependency it is failing on, then that might not fix it.
/edit: It was pointed out that this particular one last came up with someone running Nortons. I know I suggested an exclude, and this should be set in the real-time scanning function if you do that, but this is not a full test. To completely rule it out, you need to uninstall it altogether and see if it still breaks without it. Unfortunately disabling and excluding does not stop the AV filter drivers from interrogating and potentially adjusting the program as they are hooked deep in the Windows Kernel. You may need to do this so we can rule it out from being the cause.
This
article from MS, while long, explains some stuff about filter drivers and then in a small bit of text explains....

These filter drivers scan files as they are opened and closed on a hard disk. For troubleshooting purposes, temporarily remove the antivirus software
