Iam having the same problem check add and remove but cannot find smartnav there or in the program files iam at a complete lose dont think ive downloaded smartnav any tips please

Some times when the TIR drivers/sftware has not shut down properly (ou can not always tell) or if it has crashed your could get the "Can't run with SmartNav." message/error. If this happens clean out C:/temp, C:/Windows/Temp if a re-boot does not solve it.

You have not done anything wrong nor installed SmartNav (unless you have a Smart Nav of course ). Smart Nav (SN) is the daddy of TIR. SN is designed so that those who cannot use a mouse can use there head instead and a multiple of switching devices (like a suck/blow switch) can be plugged into it to replace the mouse buttons. Now SN can run TIR drivers as well as SN's own driver but TIR cannot run SN's software.

Have a look on the Smart Nav pages. I hope this helps clear some problems.

You can also try to do a ctrl+alt+del and check the running processes and you should see a TrackIR.exe, end that process.

Then the start the TrackIR software and it will work.
