If you remove the PDRTE package from a Windows system, some parts of the PDJRTE package are also removed. This removal causes the PDJRTE to be unusable.
Resolving the problem
On a Windows system, do not remove the installed PDRTE package if you want to continue using the installed PDJRTE package.
If you already removed the PDRTE package and want to continue using the PDJRTE package, uninstall the PDJRTE package and reinstall it.
