Haltech's ECU Manager and ESP both keep settings in your Windows user profile. Occasionally those settings get corrupted, and when that happens the program may not open at all, or it opens but won't work properly. Because those settings live in your profile rather than with the program itself, a plain reinstall may not clear the problem.
The fix: a reset script
Haltech provides a small batch file, packed in a zip, that clears every user profile setting for their software and puts your installation back to its defaults. It only touches Haltech-related folders.
- Close ECU Manager and ESP.
- Unzip the file and run the batch script.
- Open the software again. It will start as if it were freshly installed, so you may need to set your preferences again.
Windows may flag the script as potentially dangerous, simply because it's a batch file. That's expected. Only run a copy that came from Haltech or from us, never one from a forum or an unknown source.
Before you run it, copy your map files somewhere safe. It's a good habit before any software troubleshooting. Need the script? Ask us and we'll send it over. If the software still won't run afterward, see fixing a missing DLL or manually adding ESP firmware files.
