32 Bit Web Application Does Not Run On 64 Bit Os

[toddbailey]

Hi All,

 

I have this web application I'm revising and hitting a wall when publishing to a 64 bit machine.

It fails to run when I navigate to a page that accesses the Fusion Charts dll on the 64 bit machines

 

ON a 32 bit machine there is no issue, FC runs fine on my 32 bit Vista x86 machine w/IIS 7.

 

The 64 bit machines are Win Server 2008 R2 & Win 7.

In each instance IIS 7 was set up the same as the 32 bit vista box and

fwiw on the 64 bit machine 32 bit application mode was enabled.

 

What am I missing to set up to allow a 32 bit application to run properly?

 

The error I see when trying to access the fusion charts page (from the machine's desktop) look like this

 

Server Error in '/' Application.

Make sure the webserver is set to run scripts and programs in 32bit mode.

Make sure the webserver is set to run scripts and programs in 32bit mode.

 

 

So, How do I accomplish this?

 

In the application pool setting I have 32 bit mode enabled (true) , but I don't know how to set script & programs in iis7

 

thanks.

Additionally, I don't think this (allow scripts and programs) is a root cause of the problem, since the web site does run, meaning I can navigate through the various pages (asp.net + javascript, c# and vb or pure html) but only when I navigate to the few pages that utilize the InfoSoftGlobal.dll for charts and graphs will the error occur.

 

In the application pool there is a setting for allow 32 bit, and it is set to true, but I can't say that it changes any thing, in either case, true or false, the error message appears.

A New Development !!!

 

I tracked down where the error is coming from.

 

Just for grins, I recompilied the web application and reposted the app bits from my Win Vista x86 (32 bit os) partition

And wouldn't you know it, The Web Application runs, no errors from before.

 

So it's not a Win Server issue but something to do with the Visual Studio 2008 config/install on the Win 7 partition.

Sorry for the bother and thanks for the thoughts but I'll need to research this, and perhaps post the issue on a VS forum.

After i posted what I did I started to wonder if it was a VS issue. Thanks for letting us know what the problem was.

[toddbailey]

Since I finally got it nailed down to VS, I played around with VS configurations a bit.

Not sure exactly what eventually fixed the problem, but it could be to run VS in admin priv. mode, run in Vista SP 2 compat. mode or resetting the app build config setting. With all the new tech to play with it's no wonder something broke, being very new to R2, Win 7 & IIS 7; I'm amazed anything worked at all, even though it took me about 3 weeks to get everything installed and running. Now I can go back to my real job and write code... what a concept.

 

 

Thanks again.
