Details
This issue is caused by the isapiclient.dll that was not updated to the right achitecture during the upgrade.
To fix the problem:
- Go to the ...Trend Micro\Security Server\PCCSRV\Web\CGI\ folder.
- Look for the isapiClient.dll file and compare its file size with isapiClientX64.dll and isapiClientX86.dll.
If the isapiClient.dll is 873 kb it is using the 64-bit version, if the isapiClient.dll is 604 kb it is using the 32-bit version.
- If you are using a 64-bit OS rename the isapiclientX64.dll to isapiClient.dll.
If you are using a 32-bit OS rename the isapiClientX86.dll to isapiClient.dll.
- Restart the server. The agent should come back online.
