Re: MySQL ODBC Connector 9.1.0 - Connection Issues in ODBC Data Source Administrator and Connected Application

Hi Vinni,

I was able to figure out the issue we were having.

Overall, the VC++ version was the issue, however, the application we were struggling with is RStudio. The RStudio package included its own copies of the VC++ .dll files. These .dlls came from an earlier version of VC++.

So basically even though VC++ was up to date, RStudio continued to use old dlls so the problem remained.

We use Tableau a fair amount at my place as well and haven't noticed the issue since updating VC++. Are you using Tableau Desktop? I just briefly checked the version I have installed and I didn't see any VC++ files in the install directory but I could be missing them.

Just in case your issue with Tableau is similar - here is the bug report I submitted to RStudio that explains the problem and how to resolve it. https://github.com/rstudio/rstudio/issues/15674
