Did you check if the CyMiniProg3Service is running?
Check it (XP) under Start -> Services -> Control Panel -> Administrative Tools -> Services
Win 7 is similar but I don't have the menu path memorized.
Did you install the Cypress DVD by accident (or on purpose), or run any online updates onto your other laptop?
You can check the Cypress versions:
Cypress PC program – Start->Programs->Cypress->PSoC Programmer 3.12
- Driver Station Install 3.12.0.827 (correct version)
- Update from Online 3.12.4+ (user did an online update - incorrect)
- Cypress DVD case 3.10.0.440 (user installed the Cypress DVD – incorrect)
I haven't verified that this year hasn't changed these versions though.
