I tried to open a model I have made some time ago, but the file was not opening with version 2.3.5. Viewing the first record of the pmx file, I see it was created with version 2.1.11, so I finally opened it using version 2.2.0
Is it possible to transfer that file to the new version 2.3.5?
I tried to upload the pmx file but it is larger than 10 MB (almost 26)
Since I have several files created with older versions, so it is important for me to know if I can transfer them to the new version of the program
No, PrePoMax does not guarantee backward compatibility. That is why older versions of PrePoMAx are available online. Usually, it is possible to open old files in newer versions, but sometimes the compatibility is broken.
I built from scatch a new model in version 2.3.5. After saving it and closing the program, I was unable to reopen the file using the same version (2.3.5)
Thank you for your response. I’ll try 2.3.6 when it becomes available in the download page.
What does “sync the source files” mean? I verified that my model was built on 2.3.5.
I downloaded 2.3.5 again, but it’s still unable to read the model.
The error message in the command line is the following:

I can build again my model on 2.3.0 whitch is stable for me, but I’m afraid it will not be compatible with the newer versions.
