DLP 15.7 MP2
As of version 15.7 Maintenance Pack 2, Data Loss Prevention no longer uses Microsoft Visual Studio 2010 Runtime. This may result in not being able to run the executables in \program files \Symantec\DataLossPrevention\EnforceServer\15.x\Protect\bin
Listing below the executables in the bin directory that may not work as expected due to this behavior.
AdminPasswordReset.exe
DBPasswordChanger.exe
LanguagePackUtility.exe
NotificationTrafficMonitor.exe
ReinstallationResourcesUtility.exe
SolutionPackInstaller.exe
sslKeyTool.exe
There are two things to verify and fix.
First, ensure that the utilities confirugation file has the correct jvm path. Its found in the path "PATH_TO_INSTALLATION/Symantec/DataLossPrevention/EnforceServer/DLP_VERSION/Protect/config/UTILITY_NAME/Configuration.txt"
This needs to correctly reflect the path to the current version of java used by DLP.
Second, put the JRE bin directory path in the system path environmental variable.
For example, if it is C:\Program Files\Symantec\DataLossPrevention\ServerJRE\1.8.0_202\bin then mention it as per the below screenshots:
