PDF4Free - Path contentation results in mangled data

(need to be deeply analized- putting it as placeholder)

When InstallDrv.exe of PDF4Free package tries to install the printer driver and the printer monitor devices via a PRINTER_DRIVER_INFO_3 structure, it uses kernel32's GetEnvironmentVariableA to retrieve windir variable. Then it makes some string handling magic and contenate it with the driver name.

It fails somewhere between this step, because the resulting path populated in pConfigFile, pDataFile, pDepedentFiles, pHelpFile is all mangled. The pEnvironment (where concatenation is not necessary) and the pVersionData instead has valid data.
