Hi Sukruth,
Unfortunately project importer does not support MPC5xxx projects (it is dedicated to DSCs only) in CodeWarrior for MCUs 10.x
Anyway, there are essentially two options:
1) stay with CodeWarrior for MPC55xx/56xx v2.10
Althought Windows 10 is officially not supported I've verified it is possible to use it with Windows 10 64bit
(IDE + build tools + debugger)
I'd suggest you to try:
* to run the installer as an administrator.
* enter installation path outside of "Program Files" folder (use e.g. "C:\NXP\CW for MPC55xx and MPC56xx 2.10")
* run the installer with compatibility mode set to Windows 7 if the suggestions above do not work.
* If you install it correctly please download the latest Pemicro Drivers (PEmicro | Experts in Embedded tools for Flash Programming and Development )
2) migrate your project into CodeWarrior for MCUs v11.0
You will have to create a new project, add your source files and cofigure the project manually.
See attached document AN4094 to migrate the build tools settings - CW v2.10 vs. CodeWarrior for MCUs (Eclipse)
The advantage of option #2 is you will get the latest compiler version with many issues addressed.
If you experience any issues while migrating project we can assist you (in such a case please submit a support ticket for a private support channel: How to submit a new question for NXP Support
Hope it helps.
