3mf project opening problem

[SinaFa 0]

I installed different Ultimaker Cura versions and did not remove the previous ones as the following list: 

5.1.1

5.4.0

5.4.0-beta.1

5.6.0

5.7.0

5.7.0-beta.1

Now, I have saved different settings on each version. However, I can only open ".3mf" projects using the 5.1.1 version and cannot open them using the other versions. How can I solve this problem?

project files are not going to be fully backward compatible.. and there has been quite considerable changes from 5.1.1 to 5.7.0 so.. im not surprised if your trying to open a 5.6 or newer project in 5.1.1 and its not working..

I have another problem!

I cannot open any files saved by different versions of Ultimaker Cura using 5.7.0!

Even if I save a file in Ultimaker Cura 5.7.0, I can not open it with the same version!

Only the 5.1.1 version opens ".3mf"  files.
