What should I do if I prompt the registration control file to expire when copying tax returns remotely?

A: First of all, Shenyang users can log on to the website of Liaoning Aerospace Information Co., Ltd. to download and install the registration controls themselves. Detailed operating instructions can be found in Technical Support → Technical Hotspots → Operating Instructions for Online Newspaper Reading System Registration and Configuration on the website of Liaoning Provincial State Taxation Bureau. Users can also contact the service organization, copy the registration control file to the local service organization and paste it under the anti-counterfeiting and tax control installation path (the default installation directory of the billing subsystem is "C:\Program Files\ aerospace information \ anti-counterfeiting billing \BIN"), or they can install the service at home. Second, users who copy newspapers in different places need to go to the local service unit to copy and paste the registered control files under the anti-counterfeiting and tax-control installation path (the default installation directory of the billing subsystem is "C:\Program Files\ aerospace information \ anti-counterfeiting billing \BIN"), or call the customer service phone of the local service unit to provide installation services.
