Spark update do not work

I uploaded new spark 2.63_online to the server.

When I click yes to the upgrade prompt on the client machine - the window comes up “Download IM client” and sits there without progress bar moving.

when I click X it says that upgrade is cancelled. How do I fix this problem?

Client - Win7 64 bit, server OF 3.7 on server 2003 machine.


You may want totry to rename the client to spark_2_6_3.exe.
