Check the file
Use the current download link. Inspect the Beijing Qingruan Chuangxiang Technology Co., Ltd. digital signature in file Properties and compare the published SHA256 when needed.
Choose the application location
Run the installer, review the application folder and shortcut choices, and read Windows permission prompts. Some system actions require administrator permission.
Review the optional RelevantKnowledge offer
The installer can present a separate optional RelevantKnowledge offer with its own terms and privacy information. Read the displayed choices. Declining that offer allows the free application installation to continue.
Remove a product when needed
Use Windows Settings → Apps to uninstall the application. Any separately accepted optional product has its own entry and removal instructions. Keep your personal output files and backups separately.
