You can try to specify a "workdir=<path>" attribute within the install command. This will be used as the working directory. However as I said specifying an UNC path name (e.g. "\\server\xy") might not work for the setup. In that case I suggest the following: Write a small batch script which does the silent installation. Some untested code: @echo off echo Installing Tera Term copy "%SOFTWARE\bin\teraterm\setup.exe" "%TEMP% copy "%SOFTWARE\bin\teraterm\ttermpro.inf" "%TEMP% %SYSTEMDRIVE% cd "%TEMP%" start /wait "setup.exe" set EXIT_CODE=%ERRORLEVEL% del ttermpro.inf del setup.exe exit /b %EXIT_CODE% Then run this command script instead of setup.exe. I did not test the script above. It was just written to give you some idea. br, Rainer |
