This issue occurs due to System Environment Variables present within the Windows environment and related to Dell Compellent software. The vCenter Server 6.0 installer calls the
InstallApp-NT.bat which sets temporary parameters for the Tanuki wrappers.
These variables are temporarily used in the initial setup of Tanuki:
set _WRAPPER_EXE="%_WRAPPER_L_EXE:"=%"
set _WRAPPER_CONF="%_WRAPPER_CONF_DEFAULT:"=%"
Upon the install/upgrade, these variables are not required at runtime for the software to execute correctly.
