C# 2013 Default certificate could not be created. Publish aborting

Question

When I try to run a .exe that I built in Visual Studio 2013 with C# it will run just fine on the machine I compiled it in. When I try to run the program on different machines I get exception errors.

So I tried to publish the program and I get this error:

Default certificate could not be created. Publish aborting

If I run the executable from a machine that has Visual Studio on it it works fine.

When I try to create a certificate I get the error

The Profile for the user is a temporary profile. (exception from HRESULT:0x80090024)

I would like this executable to run at start-up on all Windows 7 student computers in our school.

You need to tell the publisher where to get the certificate from:

1. Go to Project → Properties
2. Go to the tab named "Signing"
3. Check the checkbox labeled "Sign the ClickOnce manifests". This enables the section where you can point to a certificate.
4. Click on the button labeled "Select From File...". In the directory listing, choose a key file (.pfx) and Open....
5. From the step 3, click the button labeled "More Details...". This will display the certificate you've just selected.
6. Click "Install Certificate" and follow the prompts.
7. Save and Publish your solution.
