isdone.dll error occurs: your actions?

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.

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.

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.
