Cannot compile project after change to "any cpu" randomly

Question

Hi,
in my VS 2013 i had changed the solution from x86 to "any cpu" in the debug-settings, the build-settings etc.
Now sometimes i try to build it it gives the error "Generate ressource cannot be executed because
it cannot connect to "CLR2" and Architecture "x86" - please make sure(1) runtime and architecture is avilable  and(2) the file
 "C:\Program Files (x86)\MSBuild\12.0\bin\MSBuildTaskHost.exe" exists
I do not know why that is, it should compile in x64 since my os is 64 bit. The workaround is to delete the exe in my  debug-folder and then let the vs build it again.  
Sometimes it can work for days after that workaround to build newer versions, then magically it breaks again.
Looking at the .vbproj-file from another project that was "any cpu" from the start i learned that some  x86-stuff is still in my config of the project that has the issue.
My question is now if you recommend to "just change it" or if just editing the file to look like that other project will not do it all.
My vbproj-file from my project looks like this
Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio Express 2013 for Windows Desktop
VisualStudioVersion = 12.0.31101.0
MinimumVisualStudioVersion = 10.0.40219.1
Project("{F184B08F-C81C-45F6-A57F-5ABD9991F28F}") = "SAP-Toolbox", "SAP-Toolbox\SAP-Toolbox.vbproj", "{165D1482-8BEB-4247-98EA-0A4040331290}"
EndProject

GlobalSection(SolutionConfigurationPlatforms) = preSolution

Hi mrsnipes,
According to your description, I suggest you could try to close the VS and then re-open the VS2013, then clean build solution-> re-build your solution and then check if the project/solution can be built successfully.
When I tried to change the solution platform to Any CPU, I found that it work fine. So to check if the issue occurs the specified project/solution or VS IDE, please try to create a simple new VB project in VS 2013 Express for Windows Desktop and
then right-click your solution->Properties->Configuration properties->Configuration Manager->Change the Active solution platform to the Any CPU check this issue again.
(1) If you still get same error, maybe you will need to repair or re-install the VS 2013 Express for Windows Desktop check this issue again.
(2) If you did not get same error in a new project, I doubt that this issue maybe more related to your specified project, so please try to create a blank solution and then add the project into the blank solution.
As you said the error message, I suggest you also refer the following article check if it can help you solve this issue.
