Installation Fails

I am trying to install a managed package which i created in another instance.
Previously it was installed successfully. Now i have done some changes on that instance and uploaded it again. When am trying to install the newer version the installation fails.
Below is the error which am getting..

I am also getting this error on some installations of a Managed Package.  On some accounts the package installs fine without any problems and other times we get this very vague error.


Is this an installation/packaging bug?


Hi ,


Yes. Also when am updating a package with my older version it is working fine.

But when i try to do fresh install it fails.
