Product / Version: SAP Crystal Reports 2013

Issue: Fatal Error:

Fatal Error: At least one port in the range 4520-4539 must be open for the installation to proceed. Please ensure that no application or firewall is blocking this range.

Error fires when I try to install Crystal Reports by Double-Clicking the Setup.exe file located at:C:\Users\Dr. Evers\Downloads\51046782\DATA_UNITS\CrystalReports\setup.exe

I have:

1. disabled all virus software

2. opened ports 4520-4539

3. disabled windows firewall

4. downloaded Crystal Reports (build: 51046782) from a link sent to me by an SAP support person

5. contacted that person to tell them that the install (using 51046782) still throws the same error

6. was told that I had to post this issue on this forum (thus doing so now) and then wait 24 hrs.

If anyone knows how to resolve this, please let me know; if not, will SAP support please contact me after the required 24hrs has elapsed. This exact issue was posted in 2013 but was never answered.

Thank you,
