Biztalk 2004 Load Generation Tool

There is an excellent Biztlak 2004 load generation tool available out there . I did not get a chance until recently to use it .So when we had a requirement to stress test a Disaster Recovery standby box , I downloaded the tool. The installtion gave me .

Errr 1904.Module C:\Program Files\LoadGen\ComFileMonitor.dll failed to register

After being stumped for a while I went and looked at System Requirements

- Microsoft .NET Framework 2.0

I wonder if they have a version of the tool built on 1.1 as most Biztalk 2004 Developers would have 1.1 on the box . Hopefully I can get a 2.0 box configured and test our 2004 box
