  1. Open EP-Launch in version 8.8, and go to the "Utilities" tab.
  2. Select "IDFVersionUpdater" from the drop-down list
  3. Cick "Run IDFVersionUpdater"
  4. Follow the prompts in the pop-up window to chose your v8.5 file and click "Update File"

Thanks for you answer, Anna. Your answer correctly solves my problems. It seems that we can upgrade the version of idf through using the Utility options, but i am also curious about how to downgrade the version of idf file.

It looks like it is possible, but you would lose a lot of information and potentially cause issues. Most softwares (e.g. IES) do not allow you to go backwards:
