Maybe keep running it in Windows 7 then.
Here are a few things that you can do: If you developed the solution, or have access to the source code, try to debug and see what is going wrong—in most cases, the .NET framework version is not available, or something like that.
If you do not have access to the code, or maybe bought the product, try to contact the developer and let them know you are facing this issue.
Other than that, there is little to no help that can be given on this.
