How To Resolve Isdone.dll Error in Fitgirl Repack Games
Yeah, that pesky ISDone.dll error can completely kill your installation vibe, especially when you’re trying to get those FitGirl repacks up and running. Basically, Windows throws a fit when it can’t handle decompressing or copying huge files — typically because of memory issues, missing DLL files, or system misconfigurations. This guide walks through some tried-and-true methods to get rid of that error so you can finally enjoy your new game without constant crashes or install fails. Expect to do some downloads, a bit of folder fumbling, and maybe tweak your system settings. But on the bright side, it’s usually fixable with a few adjustments—but not always straightforward, of course. Sometimes, weird things happen on different setups, and what worked for one person might not on another.
How to Fix the ISDone.dll Error When Installing FitGirl Repack Games
Method 1: Download and Replace the DLL Files
This is the classic move. The error often pops up because Windows can’t find or read the ISDone.dll or Unarc.dll properly. Replacing or fixing these files sometimes does the trick. The reason? Corrupt or missing DLLs are a common culprit for the error, especially if an install gets interrupted or files aren’t copied correctly. Expect a better chance at success if you grab the latest versions from trusted sources and place them directly into your system folders.
- Head over to Download ISDone.dll and Download Unarc.dll. Make sure you pick the latest version, preferably from a reputable DLL repository.
- Once downloaded, right-click each file, then choose Extract All if they’re in zip format, or just move them if they’re DLL files.
- Drag and drop both DLLs onto your desktop to make things easier. No more digging through folders every time.
Method 2: Copy DLL Files into System Folders
This step helps Windows recognize those DLLs system-wide, which can fix errors when it’s missing or reads the wrong version. The idea is to put these DLLs where Windows expects them—specifically in System32 and SysWOW64. Fair warning: You’ll need admin rights to do this, and messing with system files always carries a tiny risk — so make sure to back things up or create a system restore point if you’re nervous.
- Open This PC, then go to Local Disk (C:).
- Navigate to Windows > System32. Paste the ISDone.dll file here. When prompted, click Continue or provide admin permission.
- Next, go back to Windows, then open SysWOW64. Paste in the Unarc.dll file, again confirming any admin prompts.
If Windows blocks or refuses, double-check that you copied the correct files and that your user account has the right admin rights. Sometimes, it’s weird, but rebooting after copying helps the system refresh its DLL cache.
Method 3: Install the Latest Visual C++ Redistributable Packages
Sometimes, this error is caused by missing runtime components. Installing the latest Visual C++ Redistributable can fix that. Because Windows loves to break things into tiny DLLs, and if one of these is missing, errors like ISDone.dll pop up like uninvited guests.
Download and run the installer. If it offers to repair your existing installation, let it. For the best chance of fixing, find the install_all.bat file in the extracted folder, right-click, and run as administrator. Sometimes, this process is trial and error, and in some setups, it just refuses to settle on the first try. Patience is key.
Method 4: Tweak Virtual Memory Settings
If your RAM or virtual memory is just too stingy, failures happen. Increasing page file size can give your installer more elbow room—kind of like giving your system a little extra breathing space when working with huge files.
- Press Windows + R, type
sysdm.cpl, and hit Enter to open system properties. - Go to the Advanced tab, then click Settings under Performance.
- In the new window, switch to the Advanced tab again and hit Change… under Virtual Memory.
- Uncheck Automatically manage paging file size for all drives.
- Select C: drive. Then choose Custom size.
- Based on your RAM, set the values like this:
- 4 GB RAM: Initial 2048 MB, Max 4096 MB
- 8 GB RAM: Initial 4096 MB, Max 8192 MB
- 16 GB RAM: Initial 8192 MB, Max 16384 MB
- 32 GB RAM: Initial 16384 MB, Max 32768 MB
- 64 GB RAM: Initial 32768 MB, Max 65536 MB
- Click Set then OK, and restart your PC to see if it helps. On some machines, this step alone fixed the install errors, especially if they happened during large file decompression.
Other Troubleshooting Tips
If the errors persist after trying everything above, here are a few other things to double-check:
- Make sure your antivirus isn’t blocking or quarantining the DLL files or the installer itself. Sometimes AV software sees legitimate files as threats.
- Run Windows Update to patch any system bugs or missing components that could interfere.
- Run the installer as Administrator—right-click the setup file and pick Run as administrator.
Wrap-up
Fixing the ISDone.dll error often involves a two-pronged approach: replacing or fixing DLL files and making sure your system can handle large files without choking. This process can be kinda a pain, especially if things don’t work on the first try, but generally, one of these methods gets you there. Don’t forget to restart everything after big changes and keep Windows updated. If all else fails, sometimes trying to reinstall or even experimenting with lower virtual memory settings (like setting a smaller page file) can help on some setups. Of course, every PC is a little different, but with some patience, this screwdriver-in-the-system approach usually gets those game files installed without crashing mid-progress.
Summary
- Download the latest DLL files from trusted sources.
- Copy DLLs into System32 and SysWOW64 folders.
- Install the latest Visual C++ Redistributables.
- Adjust virtual memory settings for large file handling.
- Always run installers as admin and check antivirus blocking.
