The HiSuite application is still running in the background while the proxy tries to apply the patch. Step-by-Step Solutions 1. Downgrade Your HiSuite Version (Most Common Fix)
The tool lacks the necessary rights to modify files in the C:\Program Files (x86)\HiSuite directory.
You are using a version of HiSuite that is too new or unsupported by the proxy tool.
Your security suite might prevent the httpcomponent.dll from being modified.
Uninstall your current HiSuite, download an older version from a trusted repository like ProfessorJTJ's HiSuite Archive, and try the patch again. 2. Run as Administrator
The developer of HiSuite Proxy on GitHub often notes that newer versions of HiSuite (like v11.x or higher) have patched the vulnerabilities used by the proxy.
HiSuite Proxy must have permission to overwrite system-protected files. Right-click the file. Select "Run as Administrator" .
