Hi, guys  
when I have been installing dynare 4.6.4, the program auto-uninstalled dynare 4.5.7. and when uninstalling dynare 4.5.7, the process auto-uninstalled dynare 4.6.4

How to coexist the two version of dynare?

Thanks in advanced.

Which operating system are you on? In Windows that does not happen.

Via Homebrew? Or the installer?

It seems like that the 4.6.\* installer auto-uninstalls any 4.5.\* versions on MacOS, I can replicate this.

A workaround:  
Reinstall 4.5.7. Then go into /Applications/Dynare and move the folder 4.5.7 to some other location. Then install 4.6.4 and move 4.5.7 back to /Applications/Dynare.

The same is true for more recent versions like Dynare 6. Older versions will not be automatically uninstalled and can coexist with newer versions.
