" is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)"

Apr 19, 2006 04:31 PM|LINK

I'm attempting to migrate an ASP.NET application from .NET 1.1 to 2.0 (and I'm also moving the development platform from VS.NET 2003 to VS.NET 2005). After some modification the application builds cleanly on the new platform but when I attempt to run in debug mode I see the error shown below. I'm building on a new WinXP-64 machine (AMD Athlon 64 CPU).

If I change the target platform to "x86" in the solution properties, I can't build the app (hundreds of unresolved dependencies).

Can anyone point me in the right direction to solve this problem?

Many thanks

Hello

I am also having the same problem... 1.1 converting to 2.0, and 2003 converting to Vis Studio 2005. Also running 64bit Win XP. Did you find a solution?

Thanks and good luck.

I had the same problem, with a slight variation.

Porting VS 2003 to VS2005 and chaging target from 32bit to x64.

I was developing on a regular 32 bit Win XP platform for a target x64 machine.

I had to change the IIS on the x64 bit machine to run 32 bit mode .Net 2.0. Lookup the microsoft article on IIS 32 vs 64 bit mode. This may not be the best solution, but it worked.

1. Inside IIS (7) click on Application Pools.

2. Find the Application Pool that is configured for your web application in the list.

3. Select it, then click Advanced Settings on the right.

4. Second setting in the list: Enable 32-Bit Applications - must be set to True.

ASP.Net 32-bit IIS

Code On!

Is there a way to enable this option via code (VBScript) or via command-line?
