Hi, I've installed the Express version of DbForge for SQL Server, and it won't run at the same time as Visual Studio 2010 (or 2008 for that matter). When VS is running, DbForge gives the following error:

"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."



This happens as soon as I press CTRL+N to open a new query. It occurs whether the connection to SQL Server is local (same machine) or remote (LAN or internet).

Interestingly, if I start Visual Studio when DbForge is already running, Visual Studio throws the following message after a couple of minutes:



The contents of the DbForge error message is possibly indicative of some graphics driver problem?

Please try the latest version dbForge Studio for SQL Server, v3.8 Beta http://www.devart.com/dbforge/sql/studio/download.html

Thanks for the reply, alexa.

After some testing, it turned out to be an unusual issue with my graphics drivers. I reverted to a previous version of the drivers and the problem went away. All thanks to DbForge's detailed error logging, which hinted at a graphics issue.

Please let us know if any questions arise.
