Just started at a new company managing around 50 endpoints, and I've inherited some pretty outdated software. One of them is ManageEngine Desktop Central, currently sitting on build 10.0.283.

I’m trying to bring it up to the latest version, and according to the official upgrade path, my first step is updating to 10.1.2119.10. That's where I hit a wall, whenever I try to run the upgrade, it fails with:

"Signature verification for the patch file got failed"

Anyone run into this before or know how to bypass/fix the signature check for these older builds? Totally stuck here.
