[C#] An attempt was made to load a program with an incorrect format. (Exception from

I have a C# project with quite a few embedded resources, file size got rather big so i thought to compress it a bit using mpress.
These embedded resources are extracted to a temporary location when the program is run.
Unfortunately now i always get this error message: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

if i inspect the extracted resources with originals the are 100% binary the same (same hashes)

Ideas?

 

Yes, latest 2.19
Application is written as x86 executable, development is done on a x64 box though...

gonna try compressing under x86

[EDIT]
Same problem

 

Visual Studio 2010, how can i determine what architecture the 3th party dll is in? (@user_hidden, it is ProductKeyUtilities.dll from new VAMT)

 

Ok, thx...guess this explain it reason for failing, right?

Code:

Microsoft (R) .NET Framework CorFlags Conversion Tool.  Version  3.5.30729.1
Copyright (c) Microsoft Corporation.  All rights reserved.

corflags : error CF008 : The specified file does not have a valid managed header

 

origin Microsoft, without mpress it runs fine


@user_hidden
.NET 2.x as well

Besides the dll's I also packed up the 3 Windows pkconfig's files... but doubt these are the issue



On program start the dll is extracted from embedded resources to:
%APPDATA%\Roaming\KeyChecker

The pkconfig's are extracted to the same directory, little later, eg: depending on the win version they checked with radiobutton

Code:

************** Exception Text **************
System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

You compiled it for x86 or AnyCpu?

 

Plz, anyone can confirm 'ProductKeyUtilities.dll' as in VAMT 3.0 can not be used on a 64-bit OS when Visual Studio project is configured to compile as AnyCPU or x64?

Code:

Still got issues with this using mpress, SmartAssemly works just fine so i start using that
