Failed to load native dll (C:\Users\[Username]\AppData\Local\Temp\...\dbdata.dll

Question

I'm trying to create an SAConnection into a Sybase IQ database. I'm attempting to create the connection through a simple visual studio C# application.

My code fails at:

SAConnection connection = new SAConnection(connString);

And pops up with a message box:

SQL Anywhere ADO.NET DataProvider

Failed to load native dll (C:\Users\<Username>\AppData\Local\Temp\{16AA8FB8-4A98-4757-B7A5-0FF22C0A6E33}_0\dbdata.dll

Link to picture of messagebox

The code subsequently throws an exception:

"The type initializer for 'iAnywhere.Data.SQLAnywhere.SAConnection' threw an exception" with InnerException as described in the message box.

I've checked and double checked the connection string and am confident it is correct. I am using iAnywhere.Data.SQLAnywhere version 11.0.0.11292 and am connecting to a Sybase IQ database. I am running Win7 64 bit and can connect to the database without a problem in Aqua Data Studio. Any ideas on this would be great.

Answer 1

Problem solved by reinstalling Sybase IQ drivers and updating to latest version of iAnywhere.Data.SQLAnywhere.
