自定义字体的RDLC报告-调用COM组件返回错误HRESULT E_FAIL

我有一个运行在Windows Azure Web角色上的ASP.NET MVC（Razor View Engine和C#）应用程序。

我使用RDLC本地报告创建带有可打印价格标签的pdf文件，并带有相应的条形码。

在使用启动任务安装条形码字体（TrueType）后，我在Azure上使用了它。最近，它停止了工作，我没有更改任何与此功能相关的内容。

我遇到了以下错误，到目前为止我还没有找到任何解决方案。我知道问题出在条形码字体上，因为pdf是用Arial这样的标准字体生成的。此外，当在我的电脑上本地运行应用程序时，它与条形码完美配合。

我的源代码：

LocalReport report = new LocalReport();
// Rdlc file path
report.ReportPath = Server.MapPath("~/Reports/PriceTags.rdlc");
// Data source
report.DataSources.Add(new ReportDataSource("productsDataSet", dataset1));
// Some parameters
ReportParameterCollection reportParameters = new ReportParameterCollection();   
reportParameters.Add(new ReportParameter("currency", "EUR"));
reportParameters.Add(new ReportParameter("precision", 2));
report.SetParameters(reportParameters);
// FileContentResult GenPdf(LocalReport report, string filename)
return GenPdf(report, "Price Tags");

欢迎在这个问题上提供任何帮助，并对任何语法错误表示歉意。

提前谢谢。
