path that does not contain a semicolon

Steps
Look at the two installation paths
Look at the MTA folder and the GTA folder. The warning is about a real semicolon (;) in a folder name, not the colon after a Windows drive letter.

Move it to a folder without a semicolon
Only if an installation path contains ; and MTA has a problem that comes with this warning.
Use the installer of the affected one, MTA or GTA, to put it in a path without a semicolon. Keep a copy of your settings, saves and projects before you change an installation.

Point MTA at the new GTA folder
If GTA moved, choose its new folder in the MTA installer. Then open that installation and try again.
