If you keep having a problem to install an application, make a checksum to verify the package integrity by using MD5 (message digest algorithm 5th) value. Here is the instruction to get the MD5 value:
1:Click the Finder icon in your dock.Click Go in the menu bar which is at the top of the screen.
Click Utilities,scroll down and double-click Terminal in the Utilities window to open a Terminal window in your MAC system.
2:Please enter the following in the opened Terminal window:
openssl md5 /full/path/to/file
If the installer package is called FoxitReader310.enu.setup.pkg and it's in the Downloads folder, it would look like this:
openssl md5 ~/Downloads/FoxitReader310.enu.setup.pkg
3:The result should look like this:
The series of letters and numbers in the result is the MD5 value. Please help to compare it to the MD5 value provided by Foxit. Please contact Support to get the MD5 values for Foxit PDF Reader for MAC and Foxit PDF Editor for MAC installer packages.
If the MD5 value matches, that manifests your setup file is integral and not the cause of the installation problem.
Note:MD5 values are not case sensitive.
