I'm not sure if Natep's solution for CW for S12 V5.0 is applicable for CW for PowerPC:

But the symptoms were the same - "was interrupted" message. Hope it will work also for CW for PowerPC
You need to find working 32bits Win XP machine and install CW there. Then:
2) Copy whole CW folder from Win32 machine to Win7 machine (Program Files\CodeWarrior xxxx)
3) Now, this step is the MOST IMPORTANT:
Look at the file "Mwregsvr.exe" in the c:\Program Files(x86)\Freescale\CodeWarrior for Microcontrollers V6.1\bin and click the right button on this file, then click properties.
Now, in the compatibility tab,set the compatibility to WindowsXp (sp2) and set the checkbox
to run in administrator mode.
Now, click apply button then click OK button.
4) In the same folder, run once the file regservers.bat
When windows ask for the permisions, just click yes everytime.
5) You may want to create a desktop icon at this point.
