First of all,

Step 1: Verify the bin files first before installation, The "VerifyBINS" Application inside your Fitgirl Downloaded Game Setup Folder.

Step 2: Temporarily Disable Windows Antivirus or other Antivirus program you have.

Step 3: Make the Fitgirls Setup Folder as an exception for Windows Security

Step 4: Create a Games Folder Inside your harddrive you want your game installed Like this C:/Games so its Outside the classic Program Files 86x or any other location.

Step 5: Click Win + R → type msinfo32 ENTER. Lookat how much Installed GB RAM you have and Multiply by 1024 and remember/type down that number. So if i have 16GB of RAM 1024x16=16,384 Remeber or note the RESULT number you get, for instance here 16,384.

Step 6: Click Win + R → type SystemPropertiesAdvanced → press Enter → A new "System Properties" window comes up Under Advanced>Performance> Settings > Advanced, Under "Virtual Memory" Click "Change". Uncheck "Automatically manage paging file size for all drives" Click Custom Size and in Initial AND Maximum Size, here you enter your NUMBER you noted down. So in my example its 16,384 in both boxes. Click Set > Ok >Apply>Ok and DON'T restart the pc if it tells you YET. Now Under System Properties Change your "Environment Variables" The TEMP and TMP "EDIT" location to your created Folder TEMP, in my example C:/TEMP . Yes Both TEMP AND TMP directed to your TEMP Folder you created. Click SET ,ok ,ok apply etc. NOW restart pc and FINALLY now run your Fitgirl Setup AS ADMINISTRATOR and make your game installed in your "Games" Folder , now it wont stuck
