Step 1
Create a new folder on the Desktop. Put all shortcuts of the same broker in that folder to avoid the new installation overwriting the previous installation.
Step 2
Launch the installer.
Step 3
Change the new installation file directory path by renaming it. For example, add a number at the end of the installation file directory path.
Step 4
After installation finishes, close the MT4. Rename the new installation shortcut. Lastly, copy and paste back all the shortcuts in the folder earlier and arrange them accordingly.
