System.BadImageFormatException

[Glenn Palomar]

Hi,

I have VB.net application that I recently migrated from VS2003 to VS2005. It
works fine in Windows XP and 2K but NOT in XP64.

I get an exception error that says System.BadImageFormatException. I checked
the Advanced Compliler Settings and the Target CPU is set to AnyCPU. Setting
it x64 does not make a difference.

If I run my previous copy of the application built in VS2003 on the x64
system, it runs ok.

Any ideas?

Thanks,
Glenn

Strange - I posted about this very issue just a few posts above with no
response so far. I recently tried migrating my 2003 project to 2005 and I
get the same thing from one of the projects in the solution. It's an x64
system, but 32 bit Windows.

I would love to know either what causes this, the solution or where best to
look for the solution.

Hi Robin,

I found the solution to my problem. I needed to change the Target CPU from
"AnyCPU" to "x86" under Advanced Compiler Settings.

See if this will work for you.

Hi, checked it this morning, switched to x86 and still getting
BadImageFormat exception when I try to run the program in the debugger. I'm
a bit miffed to say the least.....

Actually I managed to get one to compile x86 and the program runs, but it
fails when it loads one of my libraries - I switched it's project properties
to x86, but it still seems to insist on building it "AnyCPU" regardless of
what I do! ARGGGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH.

I've almost given up on the conversion to be honest. :/
