How to ignore error due to Iprop dll?

1 min read

While working with XlsIO on 64 bit mode "Unable to load DLL iprop.dll" error is raised.

Essential XlsIO requires redistributable Iprop.dll to be installed on 64 bit windows machines. This can be resolved in two ways:

  • Place the dll on the location C:\Windows\SysWOW64

Here is the link to find this dll:

  • Use our new compound file storage

This issue with windows api dependency can be ignored by using our new compound files [.xls] storage that is implemented with fully managed code. This can be enabled by setting UseNativeStorage of IApplication as false.

Here is the code snippet:

C#

ExcelEngine excelEngine = new ExcelEngine();
IApplication application = excelEngine.Excel;
application.UseNativeStorage = false;

VB

Dim excelEngine As New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
application.UseNativeStorage = False
