MindManager 2019 Installation Question

SInce I also provide training and consultancy to clients with older versions, I personally have almost every mindmanager for windows version still installed on the same machine without any problem.

However... what would be the benefit for you to have both installed?
If you want to be sure MM2019 is really better, test it and you will probably stick with it.

Please do understand that when you doubleclick a mmap file it will open the latest version

And all the the import/export functions only work with the last installed version.

If you wish to revert to MindManager 2018 as your principal version, then run Repair in Control Panel - Programs and Features to make it the principal program.

If you do uninstall before installing the latest version, you may lose custom items you have created in the previous version e.g. Map Parts, My Maps, icons, images etc. You definitely will if you delete the previous version's user folders e.g. C:\Users\Andrew\AppData\Local\Mindjet\MindManager\18 or Registry entries. Some files or settings can be copied from the folders and more riskily the Registry to the new version if they didn't make it after the new install.

If after sometime you are happy with 19, you can uninstall and delete residual files for 18.

Jack, you may keep v. 18 as it is. The installation routine does not touch it. I'm using v. 18 now for direct comparisions and will remove it within some days.

V. 19 seem to be another sound improvement, especially in the project management arena!

My most favoured improvement is very small: The two "inserts" have been renamed to "insert" and "insert object".

Explore and enjoy it, as I do! :-)

Thanks to all of you for your replies.  I love the program and am slowly building up knowledge of the product with my eventual hope of having it adopted as a development tool at work.
