Hi @123Deepak123,
If you choose the 'CMS' option in the builder (this should be default), your component will be 1.6 - 2.5 compatible. However, this version of Cook does have some issues and lacks many features of Cook 2.0b and the forthcoming release of version 2.5 that will support all of those versions too.
it is also worth noting that the 'CMS' version will almost certainly be deprecated soon after the release of Cook 2.5. Cook 2.5 will resolve the 'open' issues listed for both 1.5 &2.0b versions in the categories listed here:

If you need any specific help with the error that you receive when you install your component, please post the details of the error in addition to your builder configuration & project/table/layout concerned.
Many thanks,
Gez
