If you want to run a 32-bit application on 64-bit OS you need to do a small change in the your project file so that this will support the application in 64-bit OS.
You can specify the software platform in project definition. To do this please open "my_project.csproj" in notepad or any other plain text editor and add the following code under "PropertyGroup" tag.
<PlatformTarget>x86</PlatformTarget>
Code will be some ting like that:
Previouse code:
<PropertyGroup Condition=" ‘$(Configuration)|$(Platform)’ == ‘Debug|AnyCPU’ "> <DebugSymbols>true</DebugSymbols> <DebugType>full</DebugType> <Optimize>false</Optimize> <OutputPath>bin/Debug/</OutputPath> <DefineConstants>DEBUG;TRACE</DefineConstants> <ErrorReport>prompt</ErrorReport> <WarningLevel>4</WarningLevel> </PropertyGroup> <PropertyGroup Condition=" ‘$(Configuration)|$(Platform)’ == ‘Release|AnyCPU’ "> <DebugType>pdbonly</DebugType> <Optimize>true</Optimize> <OutputPath>bin/Release/</OutputPath> <DefineConstants>TRACE</DefineConstants> <ErrorReport>prompt</ErrorReport> <WarningLevel>4</WarningLevel> </PropertyGroup>

This worked for me. Hope this helps!
