I'm trying to install .net connector 6.3.2 on a Vista 32 bits machine, on which I have Visual Studio 2010 Professional and Visual Studio 2008 Professional installed.

During the installation process, it fails and then roll back changes. Here is a part of the installation log file:

CAQuietExec:  Microsoft (R) .NET Framework Installation utility Version 2.0.50727.3053
CAQuietExec:  Copyright (c) Microsoft Corporation.  All rights reserved.
CAQuietExec:  The installation failed, and the rollback has been performed.
CAQuietExec:  Error 0xffffffff: Command line returned an error.

MSI (c) (4C:40) [10:13:18:255]: Product: MySQL Connector Net 6.3.2 -- Installation failed.

MSI (c) (4C:40) [10:13:18:256]: Windows Installer installed the product. Product Name: MySQL Connector Net 6.3.2. Product Version: 6.3.2. Product Language: 1033. Installation success or error status: 1603.

I tried installing the 6.3.0 and 6.3.1 versions and it did not worked either. I've read a lot of threads and bug reports about this and could not get it work. I've read that I should try renaming the "Config" folder in C:\Windows\Microsoft.NET\Framework\v2.0.50727. I tried to, but I don't have rights to rename it, even if I'm the administrator of my machine.

How to repeat:
Try installing .NET connector 6.3.2 on a machine having VS 2010 and VS 2008 Pro.

Hi Julien and thanks for your report.

Does anything from Bug#51407 helps? There was a problem with .NET FW 1.x not having connection string entry thus failing but I haven't seen problems reported for .NET FW 2.x...

Assigning Wlad as he has proper environment.

Same results under Windows 7 Ultimate (x64).  Using latest beta distribution.

Can verify on Win7 x64 VS2008 Professional and VS2010 professional installed (2008 was installed after 2010, if it matters)

Will attach the full log.
If I understand it correctly, the error is returned from custom action that tries to install assembly

MSI (s) (40:FC) [15:20:01:877]: Executing op: CustomActionSchedule(Action=ManagedDataInstall,ActionType=3073,Source=BinaryData,Target=CAQuietExec,CustomActionData="C:\Windows\\Microsoft.NET\Framework\v2.0.50727\installUtil.exe" /LogToConsole=false /LogFile=  "C:\Program Files (x86)\MySQL\MySQL Connector Net 6.3.2\Assemblies\v2.0\MySql.Data.dll")

It is followed by
Exec:  Error 0xffffffff: Command line returned an error.
ended 15:20:02: InstallFinalize. Return value 3.
and then installation rolls back

Hi guys,

I had the same problem on a Windows 7 Enterprise machine, with Visual Studio 2010 Ultimate (fresh install).

I've tried any workaround I could find, nothing working, the setup for connector 6.3.2 kept crashing when "registering data provider in machine.config".

I then installed .NET Framework version 2.0, ran the setup again, and voila! Finished successfully!

It now even shows up in the "Add New Data Source" dialog, which was what I was struggling with in the first place. Hope this helps someone...

Same thing on Seven 64bits and Vista 32bits.

How install framework 2.0 on Seven ? It seems to be impossible. I downloaded it but when I tried to install it, Windows said use control panel to activate / desactivate....

Hope we will have a solution quickly. Thank you !

It works !
What I did (I don't know why it works finaly) :
- install the actual stable version 6.2
- uninstall it
- change the directory name "CONFIG" in all c:\Windows\Microsoft.NET\Framework\old_v... to "_CONFIG" 
- Same for \Framework64\old_v
- install the beta connector => installation done !

Hope this help you

(Win 7 64bits - VS2010 - VS2008)

Hi am having the same problem using Windoas XP and trying to instal the version 6.3.6.
I had previously installed the 6.2.2 version...
Let me know if any idea of how to upgrade.
thanks you

Still not working using Connector/Net 6.4.4 and .NET Framework 3.5 sp1 on Windows 7 Professional and Visual Studio 2010. Getting 'MySql.Data.dll', or one of its dependencies, requires a later version of the .NET Framework than the one specified in the project.
