Hi,

I am having a problem deploying the assembly "Devart.Data.MySql" Version=5.70.124.0 into my shared hosting provider which is Rackspace.

I get the following error while trying to connect to the database:
"SecurityException: Request for the permission of type 'System.Security.Permissions.RegistryPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]

Thanks for your help....

The problem appears to be caused by the absence of the technical license for dotConnect for MySQL. Please add the license resource as it is described in our documentation:
http://www.devart.com/dotconnect/oracle ... nsing.html
http://www.devart.com/dotconnect/oracle ... yment.html

If there is no license resource in your web application, our components try to check whether dotConnect for MySQL is installed on your system. As they do not have the permission to check the registry, the claimed error occurs.

Could you please describe the structure of your project? As I can understand, it is a web application, am I correct?

Most likely, the problem is that you don't have security permissions for reading some of the files deployed, and this makes it impossible to check the license information. Please specify the way you added the technical license into your project so that we can suggest the exact permissions you need. For example, if you created the app_licenses.dll file, the problem may be that the access to this file is blocked.

Hi,

Yes this is a web project using MS dot net 3.5 and MySql Dot Connect EF 1 schema.

I have used the tool inside visual studio 2010 in order to create the license file (licenses.licx), The file is located in App_Data and marked as resource .

The project has hard dependency on devart dll's (Devart.Data, DevArt.Data.MySql, DevArt.Data.MySql.entity)

Thanks

Please specify whether your web application is precompiled or not. In the first case, please check that the license resource is integrated into the .dll file (there should be an entry starting with "Devart.Data.MySql.MySqlConnection, Devart.Data.MySql"). In the latter case, please check that there is the app_licenses.dll file containing the license resource in your web site.

The problem should be that there are insufficient access permissions that prevent from checking the license. If possible, please try granting full control on the file containing the license resource ([YourApplicationName].dll for precompiled web site and app_licenses.dll otherwise) to check if this is the case.

Hi,

My web application is compiled and have full DEVART references. I followed the instructions from http://www.devart.com/dotconnect/mysql/ ... tml#manual

The resource i see in the dll is MY-ASSEMBLY.licenses

I checked with license tool and it seems OK.

I cant grant any attributes nor change security policy since i am using rackspace cloud.

For me this is a license hell.....
