Note: If you have trouble accessing the downloads and get an "Manifest not available" error then do the following:
- Run Cheat Engine.
- File -> Open Process -> Steam
- Set the right-hand settings to the following:
- "Memory Scan Options": steamclient.dll (just keep pressing S when the drop-down is open to iterate through each and find it quicker)
- "Value Type": Array of byte
- "Hex": checked
- "Writable": unchecked (!)
- "Array of byte": D0 84 C0 0F 85 2E FF FF FF
- Click "First Scan". You should get a single Address and the searched Value next to it.
- Right-click the Value -> Change value of selected address(es)
- Enter new value: D0 84 C0 E9 2F FF FF FF 90
- Click OK. Done. You can now exit Cheat Engine and are able to downgrade games without the "Manifest not available" error, until you exit Steam. Continue through the guide as before.
You need to access the steam console ( steam://nav/console or steam://open/console ) and enter the following codes:
