it's been a year since you've asked this question.. but i just want to give the solution for this question...

Using Visual Studio 2010 I had to go to Project Properties -> Build Tab: Change "Platform target" from "Any CPU" to "x86"

This is a bug with Visual Studio, it seems. Here's a more elaborate thread that explains some steps you can take to fix this.

Answer 4

This error can also occur after a Windows 10 update if certain DLLs that you're using have been deregistered somehow. This is now the third time this has happened - and it causes normally fine CPU settings to appear broken.

For me this keeps happening with Microsoft.mshtml - every major Windows 10 update!! - including the April 2018.

Quick steps:

• Open developer command prompt for visual studio (as administrator)
• Run gacutil /l | find "Microsoft.mshtml"
• Go to the folder C:\Windows\assembly\GAC\Microsoft.mshtml
• Run dir and change to the directory
• Run regasm Microsoft.mshtml.dll
• Try to compile again

Answer 5

Using Visual Studio 2010 I went to Main Menu --> Build --> Configuration Manager...

From there it's pretty obvious. Theres a big table. Each of your projects is a row. Look at the "platform" column. Change those entires to match each other.
