Hi Bono

It looks like TestExecute12 is not actually installed on the machine running RemoteLaunch.

Please double-check and try again.

PayByPlate MA makes commuting in Massachusetts a whole lot easier trust me, I’ve used it on everything from weekend road trips to daily work commutes. I walked you through the login requirements for PayByPlate MA, what it is, why it matters, and how to set it up for hassle-free toll payment.

Hello,

Try re-registering the component if you know the associated DLL (using regsvr32). Reinstall TestComplete/TestExecute 12 or RemoteLaunch to ensure all components are registered correctly.
