try the following one by one: 1. check if the folder you are installing in has sufficient space, increase the virtual memory of your pc if the need be (for large games set it to 4gb atleast) 2. follow point 1 then turn windows defender off, or if you have any antivirus then turn it off. clear your temp folder. win+r then %TEMP% and delete everything inside. Now run the setup.exe as administrator. 3. If the setup complaints about missing unarc.dll or ISDone.dll do this: 2.1 Copy the unarc.dll (download from internet) and ISDone.dll (download from internet) to System32 folder (C:\Windows\System32) if your OS is 32bit, else copy the 2 files to C:\Windows\SysWOW64 2.2 open cmd and type the following: 2.2.1 FOR 32 Bits USERS - Type regsvr32 ISDone.dll (enter) Then Type regsvr32 Unarc.dll(enter) 2.2.2 For 64 Bit USERS- regsvr32 C:\Windows\SysWOW64\ISDone.dll (enter) then type- regsvr32 C:\Windows\SysWOW64\unarc.dll (enter) 2.3 if the game has partially installed, delete the installed files (if present). clear your temp folder. win+r then %TEMP% and delete everything inside 2.4 restart the system 2.5 follow step 2 4. If the above 3 fails, then restart the system in safe mode. win+r msconfig, 2nd tab check the safe mode and apply then OK. This will restart the system in safe mode. now try step number 3. 5. If you have downloaded this via torrent then recheck the downloaded file. in torrentz, click on the torrent and stop it. then disconnect from internet. now right click the torrent and select force-recheck. below you should be able to see the list of files in that torrent, if any file is not completely downloaded your installation might not succeed, if after recheck it says something like 99.x% downloaded then connect back to the internet and start the torrent. once it is finished try step number 2 6. if you have received any files with their SHA1 codes then match them after download. 7. If all these steps have failed for you, most likely your setup file(s) are corrupt.
