Component information "out of date" ??

[freeflyer]

Hello

Every time I try to import a package on a client computer by installing the server pre-built package, this is the error message I get :

"the component information in the package file is out of date.
A component CLSID or IID has been regenerated since the package was exported.
You must re-export the package"

I don't understand, since I don't do anything between the moment I export the server package and the import.

If anyone had a clue to fix it, that would be greatly appreciated.

- I don't know if that concerns that problem, but each time I install MTS, I get an error "unable to complete the registration of mmcndmgr.dll due to an unknown error".? ? ? -

Thanks for help
