Why does dotTRACE Memory always say "Connecting"?

Question

I'm trying to profile the memory usage of an IIS hosted WCF web application using JetBrains dotTRACE Memory.

In the past, I've successfully used dotTRACE Performance on this same web application and everything has worked fine, but I can't get dotTRACE Memory to start up.

All I get when I try to start the memory trace is this:

Searching through the (usually good) support documentation from JetBrains has found nothing.

Any ideas?

Server: Windows 2008 R2 (64 bit)
IIS: 7.0
dotTRACE Memory: 3.5.360 (latest available version as of today)

The application I want to provide is in a dedicated Application pool logging in via an Active Directory account.

Answer 1

dotTrace Memory 3.5 is published as x64 and x32. Which one are you using? IIS 7.0 application pool might be also x32 or x64. Which is yours? That must correspond, otherwise you will get "Connecting" and nothing more.
