Asp.NET ReportViewer :: PDF Export = System.DllNotFoundException: Unable to load DLL 'T2Embed': Access is denied

Question

I am using the ReportViewer over asp.net pages on a web hosting service.

All export works okay when I test the report on my local machine and in Visual Studio. After I FTP the web application to the remote web host the report still works but only the Excel and Word exports properly. The export to PDF or Word generates the error

System.DllNotFoundException: Unable to load DLL 'T2Embed': Access is denied

Any clues?

Answer 1

Did you send also the T2Embed.dll?

Try to modify the permissions on t2embed.dll to "READ" for "Everyone".

Answer 2

I had exactly same issue. I was using ascii char (diamond shape) as bullets inside the report footer. I removed it and every thing worked fine...

I think during pdf export because of these ascii chars the reportviewer component was trying to embed the font into the pdf file... so it needed the t2embed.dll file. in shared hosting environment permission has to be granted to use it. I even tried to upload t2embed.dll to bin folder, it did not work either and that produced 32bit 64bit issues.. needs access to IIS to enable settings.

May be old question .. Hope it helps some one :)
