The disk space requirements for installing Oracle Restart are:

• At least 7 GB of disk space

• The amount of disk space available in the %TEMP% directory is equivalent to the total amount of free disk space, minus what is required to install Oracle Restart

If the free disk space is less than 1 GB in the %TEMP% directory, then:

• Delete unnecessary files from the %TEMP% directory to meet the disk space requirement.

• Set TEMP environment variable. Go to System Properties, then Environment Variables, "TEMP=C:\Temp\."
