The largest ZEF Unity Pro files failed to be imported on UPV12, Unity Pro could crash during the import.

The ZEF files with a size greater than 3.6 MB or 4 MB couldn’t be opened and generated a Unity Pro crash with the standard Unity Pro V12.0 (*) registry configuration. It is not possible to provide a HF to solve the issue, target to this resolution is to modify the register in order to be able to open these larger ZEF files and to return to the initial values back.
To change these values use the *.reg files inside the ZIP file.

Values applied inside LargeValues.reg
AddressingSpaceSizeLarge = 0x40000000
CacheSize1stAppliLarge = 0x20000000

(*) UP V12 initial values, values found inside the InitialValues.reg file.
AddressingSpaceSizeLarge = 0x38000000
CacheSize1stAppliLarge = 0x8000000

Nota: these values are specific to UP V12.0 do not apply this FAQ to another UP version. It is mandatory to return to the initial values after the ZEF file was imported.
