Below are the steps which I had followed to resolve the issue.

  1. Download and Install pgAdmin 4

  2. Download and install Java Update 8

  3. Control Panel → System → View advanced system settings - Advanced tab → Environment Variables → System Variables → New

Enter the below two varibales in the same order:

i) Variable name : _JAVA_OPTIONS
Variable value : -Xmx512m

ii) Variable name : _JAVA_OPTIONS
Variable value : -Xms64m

  1. Click on the shutdown icon 4-5 times and ensure PEGA is shutdown properly.

  2. Then try deleting logs inside Tomcat and kafka folders.

  3. After this try launching PEGA using Startup and Login icons. You will see the PEGA login screen.
