Answer 1

For 2015 to 2010 Premium use these lines in the .sln file.

Microsoft Visual Studio Solution File, Format Version 11.0
# Visual Studio 11
VisualStudioVersion = 10.0.40219.1
MinimumVisualStudioVersion = 10.0.40219.1

Answer 2

I had some issues that were resolved by a combination of things. In my case I was converting a VB 2013 project to 2010. I solved it by:

Open the solution file in notepad (.sln) Change these lines:

• Microsoft Visual Studio Solution File, Format Version 12.00
• Visual Studio 2013

To:

• Microsoft Visual Studio Solution File, Format Version 10.00
• Visual Studio 2010

I also had to update the references. I had the issue that it give an error every time I went to view designer. In my case it was:

• Microsoft Excel 15.0 Object Library -> Microsoft Excel 14.0 Object Library
• Microsoft Office 15.0 Object Library -> Microsoft Office 14.0 Object Library
• Reassign the Microsoft Visual Basic for Applications Extensibility 5.3

This worked for me: open the solution(.sln) file with Notepad and change right values to left values in this way :

• Format Version 12.00 to Format Version 11.00
• Visual Studio 2013 to # Visual Studio 2010

and then open visual C# project file with notepad and change right value to left value in this way :

• ToolsVersion="12.0" to ToolsVersion="4.0"
