Hi

RBAViewer crashes when i try to start.

The error i get in event viewer is 1026 in .NET Runtime followed by a generic 1000 application error.  

See this thread: https://social.technet.microsoft.com/Forums/en-US/dc7cf79d-ad03-490e-a9f8-aa1ebad36889/sccm-2012-sp1-toolkit-rbaviewer?forum=configmanagergeneral

Have you upgraded to either SP2 or R2SP1 recently? If so: known issue and you will have to wait for an updated version of the toolkit.

Thanks Torsten,

yes, i have upgraded to SP2 

:-(
