I today have tried to upgrade the doConnect for MySQL from 5.70.102 to 5.70.124. During the uninstall process, the setup program failed to remove the toolbox tab. But it still moving on..... At the end of the installation, there are 2 more error boxes came out:

1. During installing assemblies into Global Assembly Cache:
"CrGaUtil.4.exe - .NET Framework Initialization Error"
"Unable to find a version of the runtime to run this application."

2. During Registering provider configuration in machine.config:
"ProviderConfig.4.exe - .NET Framework Initialization Error"
"Unable to find a version of the runtime to run this application.

I started the visual studio and have found that there no longer have choice to select MySQL as data provider ... how can i fix it??

Today I found that the problem only exist for .Net framework 4.0... After upgrading the software, the following section inside machine.config is missing:





Thanks.

Please specify the exact version of .NET Framework that is installed on your machine. Is it 4.0.30128 (.NET Framework v4 RC)? If yes, the problem is caused by the fact that the 5.70.124 build of dotConnect for MySQL is compatible with .NET Framework v4 RTM only. You may either update Visual Studio and .NET Framework to RTM or use dotConnect for MySQL 5.70.120 which is compatible with Release Candidates.
