How To Install FitGirl Games Correctly on Your PC in 2025
Installing FitGirl repacks can be kind of a pain sometimes, especially with antiviruses throwing a fit or files refusing to unzip. It’s almost like Windows has a mind of its own and makes sure you hit every possible snag. The goal here is to get the game installed smoothly so you can finally enjoy some gaming without waiting for a fix every five minutes. If you’ve run into problems like setup errors or your antivirus blocking stuff, this walkthrough should help untangle most of that mess, with steps that are practical and actual real-world tested.
How to Fix Common FitGirl Install Problems in Windows 10/11
Enable or disable your antivirus properly
Antivirus interference is probably the biggest hurdle. It’s annoying because sometimes, it just sees a setup.exe as a threat and blocks it, even if it’s totally safe. So, disable it during install, but do it the right way. In Windows Security, head over to Settings > Privacy & Security > Windows Security > Virus & threat protection. Then click Manage settings and toggle off Real-time protection. That way, your AV isn’t scanning every file as you go. Just remember to turn it back on afterwards.
One thing to keep in mind: On some machines, disabling antivirus feels like it fails the first time — you turn it off, then it turns itself back on. So, if that happens, reboot your machine, do it again, and see if it sticks. Because of course, Windows has to make it harder than necessary.
Run the setup as administrator and unblock files
Right-click the setup file (probably named something like setup.exe or similar) and choose Run as administrator. This helps bypass some access restrictions, especially if you’re installing to protected folders like C:\Program Files. Also, if Windows blocks the file from running, you might need to unblock it. To do that, right-click the setup, go to Properties, and check the Unblock box if it’s there, then click Apply.
This little step can save a lot of headaches—sometimes Windows just bats files away into quarantine without telling you.
Pick the right install folder and avoid conflicts
Choose a simple folder path, like C:\Games\YourGameName. Keep it totally separate from your Windows system folders and avoid using special characters in the folder name too. Sometimes, installing in a deep or tricky folder messes with permissions or causes unzipping errors. Also, make sure there’s enough free space—at least 20GB if possible, just to be safe.
Uncheck unnecessary language packs or optional extras unless you need them. Less clutter means fewer chances for conflicts during install.
Install needed components if prompted, but don’t panic if it fails
While installing, you might be prompted to install DirectX or Visual C++ redistributables. That’s normal. Sometimes they’re already installed, and the setup can’t tell, so it’ll error. Just click Close or Skip if the message pops up—that’s fine. If possible, manually download the latest DirectX runtime from Microsoft’s site or Visual C++ redistributables from their official page. Better safe than sorry because missing components can cause errors when launching the game later.
Set your antivirus to ignore the game folder
After installation, add your game folder (like C:\Games\YourGameFolder) to your antivirus exclusions list. Go back to Windows Security > Virus & threat protection > Manage settings > Add or remove exclusions. Pick Add an exclusion > Folder, then browse to your game directory and select it. This little step helps prevent future false positives or installation failures. Because, yeah, Windows loves to get in the way sometimes.
Re-enable antivirus protections
Once the game is installed and added to exclusions, go back and turn your antivirus back on. It’s better to have things protected, but you also need to let that antivirus relax while you play. Remember, no one’s asking you to leave it off forever, just during setup. On some setups, turning it back on causes the protections to re-engage immediately, but on others, you might have to restart your PC. Be patient.
Extra tips and troubleshooting hints
- If the installer throws errors related to
ISDone.dllorUnarc.dll, it’s almost always because antivirus is blocking files or there’s not enough RAM or disk space. Sometimes, turning off antivirus fixes it. Also, check that you have enough free disk space—at least double the size of the game files. - Sometimes, running the setup in compatibility mode for an older Windows version helps, especially if you see compatibility errors.
- Making sure your Windows is fully updated is never a bad idea—patches fix a lot of weird bugs that interfere with installs.
Wrap-up
This process might seem overkill, but it’s pretty effective in avoiding the most frustrating install errors. The key is turning off antivirus at the right times, running setup with admin privileges, and making sure your system is ready beforehand. Once you get past these hurdles, the actual game setup becomes much smoother, and you can finally get to gaming. Fingers crossed this helps someone save hours trying to troubleshoot stuff that shouldn’t be so complicated.
Summary
- Disable antivirus (Windows Security > Manage settings)
- Run setup as administrator and unblock the file
- Select a simple install folder
- Install missing components if needed, but don’t stress if they error out
- Add game folder to antivirus exclusions
- Re-enable antivirus protection afterwards
Final thoughts
Getting FitGirl games installed isn’t always straightforward, but most issues boil down to antivirus conflicts and permissions. Once everything is properly configured, launching the game should be a breeze. Hope this gets one update moving, because honestly, it’s just about following a few simple steps. Good luck, and may your download speeds stay fast.
