Hello, I have published my site, and everything working locally but now I am getting an error. Unable to load DLL 'iprop.dll': The specified module could not be found.The sever is a 64 bit, using Windows server 2008 wich does not have a iprop.dll according to msdn. Is there a way I can work around this? I currently have the following dlls.
Syncfusion.Compression.Base.dll
Syncfusion.Core.dll
Syncfusion.XlsIO.Base.dll
Thanks

Hi Whitney,

Thank you for your interest in Syncfusion products.

You can make use the code snippet given below to avoid loading of iprop.dll in 64 bit machines.

application.UseNativeStorage = false;

Please try this and let me know if you have any questions.

Regards,
Geetha

Hi Ken,

You need to set this property at our IApplication interface and not to HttpApplicationState. Please refer the code snippet given below.

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

Please let me know if you have any questions.

Regards,
Geetha

Hello,

I'm using 7.0 BackOffice and I'm getting the same error when I'm hosting my site on 64 bit server.

I didn't understand putting it at the Iapplication level.


I'm trying to create a new word document.

Example:

IWordDocument document;

document = new WordDocument();

....



Where and how would I put that code snippet. Thanks.

Hi, I am using the version 5.1.1.47 in a windows 7 pc, and Im getting this "Unable to Load iprop.dll"error.
I tried to add the line application.UseNativeStorage = false, but that value is not available for the IApplication object I use.

Thanks
