Oracle XE 11.2.0 data pump expdb works on but impdb doesn't on Windows 10

New to Oracle DB administration here. I have a fresh localhost installation of Oracle XE 11.2.0 (x64 installation from here ) on my computer using Windows 10 64-bit. I am able to connect to the DB using both DataGrip using SYS as SYSDBA user and I am able to connect using sqlplus command-line tool. I typed an admin password on installation but somehow I am able to connect using sys password sqlplus sys/sys as sysdba (as I said, I am an Oracle DB rookie). I have to import an exported EXP.DMP file from a colleague using the following command:

impdp.exe 'sys/sys as sysdba' FULL=Y DUMPFILE=exp.dmp REUSE_DATAFILES=Y TABLE_EXISTS_ACTION=REPLACE

Windows starts to complain: And the following line appears in the command line:

c:\oraclexe\app\oracle\product\11.2.0\server\bin>impdp.exe 'sys/sys as sysdba' FULL=Y DUMPFILE=exp2.dmp REUSE_DATAFILES=Y TABLE_EXISTS_ACTION=REPLACE
Access is denied.

c:\oraclexe\app\oracle\product\11.2.0\server\bin>

**Important note:** I have tried to **export** instead to exp2.dmp in order to try another command and it works with no issue:

c:\oraclexe\app\oracle\product\11.2.0\server\bin>expdp.exe 'sys/sys as sysdba' FULL=Y DUMPFILE=exp2.dmp directory=DATA_PUMP_DIR logfile=exp.log

___________ How to make the import successful? **Edit:** I have noticed something very odd in the C:\oraclexe\app\oracle\product\11.2.0\server\bin folder. I have installed the database engine using setup.exe and everything went smoothly. What's going on? Can I download the file anywhere for 11.2.0 XE without the un/installing again which would take another hour?
