Error message shows that missing paraffin.exe (v3.13). I’m unable to find any download link of paraffin.exe (v3.13) from Wintellect.com or anywhere else. It seems no longer available, except the newest version (v3.71). But the new version is incorrect and won’t work. Could anyone help me to find paraffin.exe (v3.13) or earlier version? Or any other soultion to fix this issue?
Duplicati 1 is no longer supported, though there are a few forum members who have used it in the past - hopefully one of them will be able to give you hand.
Is there a particular reason you’re not using Duplicati 2?
Unfortunately, paraffin is not open source, which is why it is no longer used in Duplicati.
Your best bet is to fix the build script to use the latest version, as it would technically be a copyright violation if anyone (other than the Paraffin author) publicly offers a downloadable copy.
