I need a visual studio expert

Job ID: 32488619

Budget: $30 – $250 USD

hello,
how are you, File is attached. I need it to be back in visual studio so I can make changes and publish it. I have tried with dotpeek but I cannot edit the forms and it comes up with errors when I try to publish it. I don't have any experience in reverse engineering so I need help. I will need the VS file when complete and it will need to be error free. Can you help? Thanks

This is the installation file https://www.stromamembers.co.uk/downloads/fsap2012/publish.htm
