Open newer Premiere Pro CC 2015 work file in an older version

Dec 2017 Update: You can use the below method to convert Premiere Pro CC 2018 to Premiere Pro CC 2017, just change the number “34” to “33”, but if CC 2018 features were used in the .prproj file, there will be an error when you try to export the timeline. 

Jan 2017 Update: You can use the below method to convert Premiere Pro CC 2017 to Premiere Pro CC 2015, just change the number “32” to “30”.

Here’s a quick solution on how to change a Premiere work file that is saved on a newer version to work on an older Premiere Pro version, without exporting any EDL or XML.

For this example, let’s say I need to open my Premiere Pro CC 2015.3 10.3.0 (202) .prproj file on a Premiere Pro CC 2015.2 9.2.0 (41).

  1. Duplicate the work file, change the extension from .prproj to .zip.
  2. Open with 7zip. (I got feedback that this only works on Windows)
  3. Open the file in the zipped file with any simple text editor like notepad.
  4. Refer to pic below, change the version number from “31” to “30” and save.
  5. If you can’t save it, extract the file out and make the change, drag it back in the zipped folder to replace the text file.premiere-convert-project-file
  6. Close the zip folder and revert the file extension from .zip to prproj.
  7. You can directly open it in Premiere Pro CC 2015.2 9.2.0 (41) already.

How do I reinstall Premiere Pro CC 2015.2 (9.2)?
Here’s how to get back to Premiere Pro CC 2015.2 9.2.0 (41), at this page, download Adobe Premiere Pro CC 2015.2 Update

If it is an older version than 2015.2, change the version number down accordingly to how many updates that Premiere had previously released.

Here’s the list of version numbers as listed by Eberswalde in the Adobe Forum
Premiere Pro version numbers:

  • 23>CS5
  • 24>CS5.5
  • 25>CS6
  • 26>CC
  • 27>CC 2014




  1. This is great, thanks very much for sharing!

  2. Thank you so much!!!

  3. OH!!!!
    This is what I wanted to solution!!!
    I did solve the problem!!!
    Thx Bro!!!

  4. Thanks for this! It worked! I was able to open a 2017 version created from a Mac using my Pro CC 2015 version (windows).

  5. Thank you, I have done this and changed to 25 for CS6 and it is still not opening, saying the file may be damaged or have outdated elements. Any suggestions? Is there other text that can be changed? Thank you =)

    • If you are using many new features that are only available in newer versions of premiere pro it won’t be possible to convert your file back to an older version.

    This is a totally brilliant workaround – in my humble opinion as a broadcast editor … legendary :-)!!!

    Money and freedom is the best way to change, may you be rich and continue to guide others.

  10. Superb post but I was wanting to know if you could
    write a litte more on this topic? I’d be very thankful if you could elaborate a little bit more.

    Thank you!

  11. I made a tool which does this automatically. It’s here:

  12. Hey! I would reallly need for this to work, but when i use 7zip in a mac it doesnt open in a folder just in a file that can open with notepad… and at the end it doesnt work…any ideas?

  13. For mac users:
    -change .prproj to .zip
    -open this new file in Sublime editor with XML syntax
    -change number of version as it is described in original post
    -save with prproj extension
    -smile 🙂
