部署后PDF创建功能崩溃

Question

I have method, which creates a pdf file from the view, based on information retrieved from the model. It works without any problem on my pc in debug mode, however after deployment on IIS server (different machine) it started crashing. I have granted full access to all user on a map with assembly but it didn't help. Error message is useless it only says that "something went wrong"

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

My Code:

    [HttpPost]
    public ActionResult EmployeesForExamination(List<EmployeeListForHealthExamination> model)
    {
        List<EmployeeListForHealthExamination> listForPrint = new List<EmployeeListForHealthExamination>();
        foreach (var item in model)
        {
            if (item.printDoc)
            {
                return CreatePDF(item);
            }
        }
        return View(model);   
    }
    [AllowAnonymous]
    public ActionResult ReportForHE(EmployeeListForHealthExamination model)
    {
        using (var db = new HRMEntities())
        {
            model.harmingFactorList = db.EmployeeHarmingFactors.Where(e => e.EmployeeId == model.EmployeeId).ToList();
            return PartialView("Partial/_ReportHE", model);
        }
    }

    [AllowAnonymous]
    public ActionResult CreatePDF(EmployeeListForHealthExamination model)
    {
        return new ActionAsPdf("ReportForHE", model)
        {
            FileName = model.FirstName + model.LastName + "HealthExamination.pdf"
        };
    }

此问题可能是因为服务器上缺少旧版 Visual c++ 的 Visual c++，请尝试升级它。
