Blocking Error: Patcher Won't Run After Upgrade

[Noggog]

So you upgraded something, and now your patcher won't run due to a "Blocking Error". What are your options?

[Noggog]

This happens when the patcher's code cannot compile with the current Mutagen libraries you're trying to use them with. This is normal, and usually just means you have to set it to use older versions until the patcher developer updates.

Make sure you are running on the newest Synthesis UI exe

Make sure to upgrade to the newest UI
Lots of times the newer exes will have extra compatibility logic that older ones will be missing.

Follow the Recommended Versioning Patterns

Try Setting the Patcher to "Match"

This will tell the patcher to use the versions/libraries it was originally coded with.

Upsides:

• Has a high likelihood of working, as Synthesis is setting it up to run as close to how it was coded as possible.

Downsides:

• It won't get any bugfixes/optimizations that newer libraries offer

Locked

If you cannot interact with the above controls, it's likely that you received your profile from a distributor that locked the setup to avoid accidental modifications. You can override this by going to your profile settings and unchecking "Lock Versioning"

Fall back to known working setup

Synthesis has a button in a patcher's versioning area called:
"Set to Last Successful Run"

Assuming you've HAD a previously successful run on the patcher, it will be able to set all the settings to point to that setup explicitly.

Try to Discern Why the Patcher is Unhappy

You can click the "Blocking Error" text, and usually it will give some detail text on why the patcher is unhappy.

Usually, though, it just means the patcher can't compile against the newer code. In this case, setting a specific older Mutagen version, or selecting "Match" as described above is your best option, until the patcher devs do some work to upgrade.

first time using this tool, got "blocking error" and "Path does not point to a valid repostory", I am pretty sure the url of repostory path is correct

Tried setting the Patcher to "Match", nothing different happens

Did you add the patcher via the git patcher browser system, or type in the addresses yourself? Can you take a picture of your patcher's detail pane?

I persume it suppose to be proxy issues, I have downloaded patchers manually
