FAQ

Download and install

Which systems are supported?

Windows 10 or later (64-bit), and Macs with Apple silicon. There is no build for Intel-based Macs at the moment. See System requirements.

My system warns about the installer or says "unidentified developer"?

The installers are not code-signed yet. On Windows, choose “More info → Run anyway”. On a Mac, right-click the app and choose Open; if that doesn't work, click Open Anyway under System Settings → Privacy & Security. Make sure you downloaded the installer from the official site. See Install and first launch.

Account and subscription

How do I get an activation code? Is there a free trial?

You can buy activation codes, and new users can also get a free trial code from support. See pricing and contact support.

I only see the activation screen after signing in?

Your account has no active subscription (never activated, or expired). Enter a code on the activation screen and click Subscribe Now. See Activate a subscription.

How do I renew?

Open Settings → Subscription, click Redeem and enter a new code. The remaining time is added on automatically. See Renew.

Can I use it on two computers at once? How do I switch computers?

An account can only be signed in on one computer at a time; signing in on a new computer signs the old one out. Your subscription, live rooms and mode setups are stored in your account, so just sign in with the same account on the new computer. There is no need to activate again. See One computer at a time per account.

Signing in says "This account is in use on another device"?

The account is in use on another computer. If you want to use it here, click Sign it out and sign in. If that computer is collecting, its collection will stop.

The sign-in screen keeps showing a network error?

Check your network first. If you still can't sign in, switch Network Route at the bottom of the sign-in screen to Backup and try again. On Windows you can also run the Doctor tool described below.

I forgot my password?

Click Forgot password? on the sign-in screen and set a new password with the code sent to your email.

Collection and network

Clicking Start says "The collector is offline — start collecting first."?

You need to connect to your live room before starting a round. Click Start Collecting in the bottom bar and wait for Status: Connected, then start the round. See Start and stop collection.

Can I start collecting before the anchor goes live?

Yes. The bottom bar shows Status: Waiting for live and connects automatically once the LIVE starts. See Waiting for the LIVE.

Route One or Route Two?

Route Two (browser popup) is the default. If Route Two can't connect because of a captcha, a login prompt or a network problem, switch to Route One. If Route One says Can't get the live status, switch to Route Two. See The two collection routes.

Route Two can't collect from an 18+ room?

Log in to a TikTok account aged 18 or over in the collection window, or switch to Route One. See The Route Two collection window.

The collection window says I'm watching this LIVE in the TikTok app?

This page appears when the TikTok account logged in to the collection window is watching the same LIVE on a phone at the same time. It doesn't affect collection, so you can leave it. Don't click the page's button to watch on the computer instead; that would kick out the viewing on your phone.

Collection fails because your network needs a proxy to reach TikTok?

The app has no proxy settings of its own. Switch your proxy software to TUN (virtual network adapter) mode so all of the computer's traffic goes through the proxy, then start collecting again.

The bottom bar shows "Status: Server unreachable"?

Live messages are still being collected but can't reach the MCA Plus server, so cloud widgets and Reports won't get new gifts for now. Check your network; once it's back, the app uploads the missed gifts automatically. See Server unreachable.

Do I need to end things manually when the anchor ends the LIVE?

No. When the LIVE ends, collection disconnects and the session ends automatically. See Disconnects, reconnects and ending the LIVE.

Widgets

The widget in OBS is blank, or the score stays at 0?

Check in this order:

1. The bottom bar shows Status: Connected, and you've clicked Start for this setup on Home.
2. Widget images and fonts load from the internet. On a slow connection they appear a bit later; wait a moment, or refresh that browser source in OBS.
3. A widget link belongs to the account that was signed in and the setup that was selected when it was copied. If you've switched accounts or setups, copy the link again.
4. Whether the bottom bar shows Status: Server unreachable.

See Widgets and OBS.

Windows Doctor

The app can't reach the server or keeps showing network errors. How do I check?

After installing the Windows version, the Start menu has MCA Plus Doctor (named "MCA Plus 急救箱" on Chinese-language Windows). It runs separately from the app, so it works even when the app won't open:

1. It automatically checks the network and environment between this PC, the MCA Plus servers and TikTok.
2. To fix problems it finds, click Fix all, or select an item and click Fix selected. Some fixes need administrator rights, and Windows will ask you to confirm.
3. The report is saved to your desktop automatically (a .zip whose name starts with "MCA-Doctor-Report"). You can enter your email under Account email (optional) so support can find your account, then send the report to support.

The Doctor tool is Windows-only for now.
