Enviro, thank you. You are a prince among men. A saint. A God. You are Jesus, Mohammed, Confucius and Shakyamuni rolled into a ball and smothered in a creamy sauce of really great guy. I have lost nights of sleep over this. I have tried everything and spoken to everyone who would listen. Not only that, but you fixed a random
error on my computer that had been happening since the day I bought it, through at least 3 reformats. I'm so happy, I'm nearly crying. Sweet blessed relief.
Ok, enough gushing, here's what I did:
1. Disabled debugger logging, as per Enviro's instructions
2. Opened the DT4 installer
3. With the installer open, copied SPTDinst.exe from the temp
4. Ran SPTDinst.exe from the command line with the /add switch (it refused to work any other way)
5. Rebooted, reinstalled DT4 and now it's humming away happily.
I saw at least one other person getting exactly the same
error I was (entry_point_not_found), and plenty of people are getting the kernel debugger
error, so hopefully Enviro's inspired advice will spread joy to the masses, and not just me
