No mode specified when uninstalling/installing langpack

[davcha]

Hello,

I recently upgraded my instance of SugarCRM from 5.0.0b to 5.5.4 and now i'm trying to install the updated FR langpack.

When I'm trying to uninstall the old 5.0.0 langpack or when I'm trying to install the new 5.5.4 langpack, i keep getting the same error message : no mode specified.

I've checked all the permissions in the whole SugarCRM directory (including root directory).
I've repaired/rebuilt all SugarCRM using Quick fix and repair and rebuild config file.

I keep getting the same error message.

Anyone can help me ?

Thanks

I've been able to solve this problem using firefox instead of IE6 with windows server.

But now, i have another issue : someone removed the old langpack zip file (SugarCRM-5.0.0b-LangPack-fr_FR-2008-03-02) and i cant find it anywhere...

Edit : Found it. Thanks, it works now.
