'ServerProperty' with 'Name' = 'Language' does not exist in the collection

Question

LS,
One of my customers (using ssas 2012) is facing collation issues which result in missing facts in the cubes. I suggested them  to have a look at the Analysis Server Properties. Howevere, on selection of the Analysis Services Properties page 'Language-Collation',
it doesn't open the page showing the properties, but instead the following message pops up:
'ServerProperty' with 'Name' = 'Language' does not exist in the collection
Any ideas on what could have caused this and how it can be fixed ?
We're considereing a restart of the SSAS server, but need to be very carefull because it's their production environment.
Appreciate your help,
Kind regards,
Cees

Answer 1

I am also experiencing this error when clicking on the Language/Collation page of the Analysis Services Properties dialog.
I suspect this is causing some other strange behavior such as an "invalid characters in hierarchy names" error when deploying an SSAS database, when the same solution/project can be deployed successfully from other machines. In that case, there are parenthesis
in the attribute name but no user-defined hierarchies. Error:
Errors in the metadata manager. The name, 'Project ID (Description)', for the cube hierarchy is not valid because this name is a reserved word, contains one or more invalid characters (.,;'`:/\*|?"&%$!+=()[]{}<>), or is longer than 100 characters.
I would like to avoid having to re-install SSAS if at all possible. Any help is much appreciated.
