When installing the 6.30 demo, I ran into an error right after the Installing License... portion of the installation.u00A0u00A0I received the following error:
WARNING 2004-01-09 14:48:44
Error 5 (Access is denied.) in execution of a 'CreateProcess' function,
line (262), with parameter
(C:/DOCUME1/t8881sb/LOCALS1/Temp/sapinst_exe_2/SAPCAR.exe -x -v -g -i -n
-R C:\usr\sap/C11/JC00/j2ee/os_libs -f SCSCLIENT.SAR,).
After much investigation, I simply ran the SAPCAR.exe in command-line mode from the directory where the SCSCLIENT.SAR file was located.u00A0u00A0I then went back to the installation program and pressed the ignore button. The installation then finished without any issues and worked.
I do not have the answer as to why it occurred on my machine (other machines of mine had no such problem), but at least there is a work-around.
