(Un)Installing MySQL for Visual Studio problems

[Nick Thissen]

I am trying to install the latest version of MySQL for Visual Studio (1.2.4), but I am failing in every step.


1. Install of the application fails with no real error and does a rollback. Application is not installed after. Using logging I can see the following error:

System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\Program Files (x86)\MySQL\MySQL for Visual Studio 1.0.2\Assemblies\v2.0\MySql.Data.dll' or one of its dependencies. The system cannot find the file specified.


2. I still had version 1.0.2 installed so I tried removing this. Same problem, it does a rollback.


3. I tried to uninstall via the MySQL Installer software (latest version). This also fails, with no error messages except "Failed".


4. I tried upgrading to 1.2.4 via MySQL Installer: also failed.


5. I tried to uninstall v1.0.2 with some other software (Revo uninstaller etc). Now my system can no longer see that it has been installed, but the installer for 1.2.4 still fails. Further, the MySQL Installer still thinks it is installed and does not allow me to Install it (because it already is), and Update (to 1.2.4) or Remove still fail.


I am at a loss. How can I completely remove MySQL so I can simply start over? My system is unusable now as I need MySQL for Visual Studio 2015.

Please help!
