cannot start profiling asp.net applications .net 1.1

john austin · August 30, 2007 5:09AM

Each time I try a start to profile a 1.1 web application I can the following error.

Unable to find an entry point named 'Wow64DisableWow64FsRedirection' in DLL 'kernel32.dll'.

Any suggestions?

thanks

Hi,

I'm guessing you're running on Windows 2003 Server there, in which case could you check you have at least Service Pack 1 installed?

Thanks,
Rob

Good one! This happens when you profile Windows 2003 64-bit editions without SP1 installed. Here are the details and workaround:

Thanks for this.
We are on Windows2003 without SP1, which I am installing now.

But it is not the 64 bit edition

Hi,

The issue in the KB article Brian referenced does actually apply to 32-bit editions of Windows 2003 as well, so hopefully that should still solve your problem.

Thanks,
Robert

Interesting... why would you disable folder redirection on a 32-bit system, given folder redirection wouldn't be necessary?

Robert C · August 30, 2007 6:45AM

I think technically we didn't need to, but the logic is - from what I remember - "If it's not explicitly running in WOW64 mode (i.e. forced to 32-bit), disable folder redirection".

I guess it's a slight bug, but not one that appears unless you're pre-SP1.

Is there a work around that does not involve installing SP1 ?

Could take a while on my customers server

thanks

Brian's KB suggestion of forcing 32-bit (even on a 32-bit server) I believe should fix it, though I haven't tried this myself for a while.
