MiKTeX and proTeXt ⇒ Problem with installing packages

[juliette]

Hello,
In the MikTeX package manager, I right click on any uninstalled package and press 'install' , then press 'proceed' , then it starts 'downloading' and says:

installation directory: "C:\Program Files (x86)\MiKTeX 2.7"
package repository: ftp://mirror.ox.ac.uk/sites/ctan.org/sy ... /packages/
DBlight digest: f08a6cb1159597c45a9dec162df01531
going to download 35593 bytes
going to install 11 file(s) (1 package(s))
downloading ftp://mirror.ox.ac.uk/sites/ctan.org/sy ... s.tar.lzma...

Then I get the message "unknown MikTeX exception"

And this happens no matter what online repository I use.

Has anyone come accross this problem in MikTeX 2.7 and knows how to fix it ??

Thank you/

Sometimes it helps to wait a while and retry later on. An upgrade is always recommendable.


Best regards
