Downloaded this today but have not been able to install it , whenever i click on the signature.nsf  to open it  , it crashes my notes client .

Am on R8.5 on both desktop windows 7 and laptop windows 8. the furthest i have gone is copying it on my server's domino data directory by ftp  (i cant even open it on my desktop to do a lotus copy ) and signed it otherwise i cant open the file , so i cant configure it.
