Hi i have a webapp and i use integrated web sever.

i put this app on a server with Windows 2008 server r2 64bit and app not work and show nilObject…
i have set the port of webapp to 9999
can anyone has the same problem ??
ps. i use the lastest versione of RS

i’m only one that has this problem ??

I have solved buy installing realstudio on server and recompiling on server the application. :frowning:
no good solution…
to customer service:

I changed this to the “Web” channel. I have not heard of this issue before.
