When installing an OfficeScan agent through the browser-based installation method, the customer gets the following error:
Unable to install the Trend Micro Agent
There is insufficient disk space on the target drive.
Contact your OfficeScan administrator for assistance
The error occurs even if there is enough disk space available in the C:\ drive.
The client installation path is in ofcscan.ini under PCCSRV\:
[INI_CLIENT_INSTALLPATH_SECTION]
WinNT_InstallPath=
If you do not change the value, the default is "$ProgramFiles\Trend Micro\OfficeScan Client".
If the installation path has been set to an absolute path like G:\ProgramFiles\Trend Micro\OfficeScan Client, and the keyword "$ProgramFiles" is not used, then the agent will try to install on the G:\ drive.
However, on some agent machines, G:\ drive does not exist, causing installation failure.
To resolve the issue, change the installation path back to its default value.
There are two (2) "WinNT_InstallPath" keys in ofcscan.ini. The following are their default values:
- [INI_CLIENT_INSTALLPATH_SECTION]
WinNT_InstallPath=$ProgramFiles\Trend Micro\OfficeScan Client - [INI_CLIENT_DEFAULT_INSTALLPATH_SECTION]
WinNT_InstallPath=$ProgramFiles\Trend Micro\OfficeScan Client
