1. If you are using VS2013, you may have this error since there's no template for VS2013

2. Go to folder:

C:\Program Files (x86)\SAP\SAP Business One Development Environment\SAP Business One AddOnInstaller Wizards\SAP Business One AddOnInstaller .NET Wizard\project templates

3. Copy the folder VS2010, and Paste, rename it to VS2013 (durring installing B1DE you have set name as VS2013)
