[Error] Failed to execute "C:/

Hi, I've had ISBoxer for a few weeks now dual-boxing about every day for that period of time. I know how to correctly set profiles and export them to innerspace through the quick setup wizard in the ISBoxer toolkit, and have used the profiles I'm trying to execute many times before. Two days ago I tried launching my rogues' profile the way I had been for the past few days, and came across an error message(see below). I tried this with all of my profiles to get to the same result.

Process:

[Right click] Innerspace toolbar button
[Left Click] ISBoxer Character Sets>Rogues
Wait 13-17 seconds
This message is displayed

Nothing happens after this(two times I've tried one WoW window is opened while the error message displays and doesn't open the second window)

What I've tried to fix it:
Looked at paths to WoW.exe.
Reinstalled ISBoxer and Innerspace.
Searched Google to no avail.

Can anyone help me with this?

So this happens only on the second (or more) client? Interesting...

Well, the only known reasons for this error to occur are from other software installed on your system, usually something with a system-wide hook that happens to not be compatible with Inner Space. (Most system-wide hooks are fine and there are many programs that do this.) ThreatFire for example (an Antivirus program) will cause this on every instance, even if it is disabled -- it has to be completely uninstalled for the system-wide hook to be removed.

The dev build of Inner Space does improve compatibility, and has resolved a similar issue for at least two other people that I'm aware of. To try it, right click IS and select Patcher, check "Download development (test) patches", then close and re-start Inner Space. (The setting does not take effect until restart)

It only appeared on the second client a few times, most of the time it doesn't launch the first. Developer test works though, thanks n__n
