Error "is not a valid Win32 application"

[doiley]

Hi there,

I'm currently trying to get the 64-bit pdf viewer working. I'm using VS2008 C#.

I'm running Windows 7 x64, i previously had the "Self-Registration failed" error message but read the post here: https://forum.pdf-xchange.com/ ... 067#p34067 which solved that.

Now i get the following error when the designer calls "((System.ComponentModel.ISupportInitialize)(this.pdfViewer)).EndInit();" :

"is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)"The exception is of type "BadImageFormatException"

Can someone point me in the right direction please.

Thanks,

EDIT: Also note that I have tried just using it in a brand new application without any other controls on the form.

Dale.

Hi,

I've actually solved this myself.

It had nothing to do with the dll being used. It had to do with the target CPU.

The whole project was for x86 only but because the project output was set to Any CPU it actually tried to run as 64-bit and would fail.
