[Chennaipy] reg-Invalid class string error

[JakkampudiKiranKumar at Eaton.com]

Hi ,

I am getting an error mentioned below while using in some of the machines when trying to open the application where as it is working fine in some of the machines :

I also tried to create the Class id manually using the regedit but it didn't worked.
I am using win-7 32 bit OS , python 2.4.4,Pmw module and  pywin ,pyinstaller,pythoncom..etc
Can you suggest how to force the class Id in to valid string either through code or manually by dll registration?

Thanks in advance
