The error message "this installer installs an older version (7.14.14.314). You must first uninstall the previous version" (image text). The error message is "OA 7.14.14.314 ".

Due to the test, the computer has installed multiple versions of Tongda Oa. Today, you need to reinstall Tongda 2013 enhanced edition. The following message is displayed, indicating that the software cannot be installed.

After carefully reading the prompts, it turns out that there is a high version of installation, so it is not possible to install a lower version. One was installed before the test of Tongda 2015, which is higher than this version. It should be 8.0.

I did not find the co-loading location in the control panel. It may be a long time and some information is incomplete. How can I unload this 2015?

Suddenly, some software has the installation function and the uninstall function. Run Tongda 2015. After some tests, a prompt is displayed, indicating whether to install, fix, or uninstall the service. Choose "Uninstall". Everything is OK.

Once uninstalled, run the 2013 enhanced version installer again.
