5 easy options to fix 'isdone.dll' error

Here are 5 methods of how you can fix this issue. Choose the most suitable for you!

1. Use SFC

If the "isdone.dll Windows 10" problem is somehow related to the system files, the System File Checker tool can find the corrupted system files and fix them. This tool is included with Windows 10 and is free.

To use this tool, the first step is to open a command prompt as administrator by pressing the Win + X keyboard shortcut and type sfc /scannow. After that, click on Enter and quietly wait for the verification results.

You can also use the Deployment Image Servicing utility if the System File Checker did not work as expected. The required command for this looks as follows: DISM.exe / Online / Cleanup-image / Restorehealth and press the Enter key.

If this doesn't work for you and the isdone.dll error is still bothering you, use the following advice.

2. Try to operate in safe mode

Working in Windows Safe Mode can help you, as only basic system programs and services are running in this case. That is, the possibility of conflicts between third-party software and the game installer is minimal.

To start installing the game in safe mode, you need the following:

Press the Win + R keys to open the Run window and enter "MSConfig"; then click "OK". You will be taken to the System Configuration window. Click the Boot tab and check the Securebox and the Minimum radio button. Next, to confirm these actions, click the Apply and OK buttons, and then select "Restart" to get into safe mode.

After that, reinstall the problematic game, and be sure to deselect the Secure Boot option before restarting Windows.

3. Change paging size

Expanding the paging file will help increase the amount of virtual memory and thereby increase the amount of hard disk space for virtual memory. That is, this action can solve the problem of insufficient RAM. So, from the beginning, type sysdm.cpl in the Run box and hit enter. In the new window, click the Advanced tab and then the Settings button for Performance.

Then re-select the "Advanced" tab and click the "Change" button, where you'll uncheck "Automatically manage paging file size for all drives". Next, you need to select the Custom Size radio button and change the Initial Size to a higher value than the currently assigned value.

The maximum size value depends on the amount of RAM on your computer, with Windows limiting your page size to three times the amount of RAM. Then confirm all changes and restart your computer.

4. Turn off antivirus and firewall

Third-party antivirus software can block the installation of some games. Disabling third-party antivirus (at least temporarily) can fix the ISDone.dll error.

How to properly disable your antivirus can be found on the official website of the manufacturer of this application. Follow the presented algorithm, and you will not have any questions.

It should also be noted that Windows Firewall can also block the installation of a genuine game. You can also turn off Windows Firewall and see if it affects the installation of the game or not. To do this, type "Windows Defender Firewall" in the search box and click the result for Windows Defender Firewall. Next, click Turn off Windows Defender Firewall and click OK.

5. Replace corrupted ISDone.dll

Re-registering DLLs can also help you if it's damaged. This can be done as follows:

Start Command Prompt and select Run as Administrator and type "regsvr32 Isdone.dll" into the Command Prompt and press Enter.

Then type "regsvr32 unarc.dll" in the window and press Enter.

After these steps, restart Windows and try to install the genuine game in the usual way.
