even if you were able to download an Acer erecovery software version, you will be facing the same issue, your recovery partition is missing or corrupted or not listed on windows recovery xml file.
please post a screenshot of windows disk management
windows logo key + x
Disk management
if a recovery partition of about 16GB is missing, you lost any possibility to create a factory reset media.
what's your actual OS and/or your previous OS?
