Cause
Normally, this error occurs due to improper removal of MySQL ODBC connector. If you have not removed it properly for the first time, the entries related to ODBC will not be deleted from the Registry. Due to the presence of older entries, it skips the installation process of MySQL ODBC connector from the next installation.
Solution
Please remove or rename the below mentioned entries from Registry.
- HKLM > Software > Wow6432Node > ODBC > ODBC.INI > SGDBConnection
- HKLM > Software > Wow6432Node > ODBC > ODBCINST.INI > MySQL ODBC 5.2(w) Driver
- HKLM > Software > Wow6432Node > ODBC > ODBCINST.INI > MySQL ODBC 5.2w Driver
After that try to reinstall it using VembuOnlineInstaller on top of the existing installation. Once the installation process completes, please try logging into the web console by providing correct credentials.
