Hi @qi_chen,
There may be multiple reasons for this issue. Here are the most common ones + possible solution:
- Installer was corrupted during download
- Download the package again
- Temporary folder is write protected
- Choose a writable location (e.g. My Documents)
- There is no sufficient space on the drive that hosts TEMP folder
- Free some disk space on the drive where the TEMP directory is located
If none of the above worked try opening the installer with a file archiver and extract its content on your local disk. There should be 2 folders: "Installer Data" and "Windows". Open a terminal window inside the "Windows" folder and launch the installer by running the following command:
"FreeMASTER 3.1.exe" LAX_VM resource\jre\bin\java.exe
Hope this helps,
Iulian
