Download Isdone.dll 64 Bit Windows 10 May 2026

Hope this saves someone from malware. 👍

I keep getting the "isdone.dll" error when trying to install a large game (FitGirl repack). The error says something like "An error occurred while unpacking: Unable to execute file in temporary directory. Setup aborted."

Hi everyone,

Before anyone tells me to download from a "DLL download site" – I know those are full of malware.

[SOLVED] Need isdone.dll (64-bit) for Windows 10 – Setup keeps failing download isdone.dll 64 bit windows 10

Do download isdone.dll alone. That's a trap.

No legitimate Windows 10 system includes isdone.dll by default. If a website tells you to "download isdone.dll for Windows 10 system32", they are lying to infect your PC. Hope this saves someone from malware

I know this error is usually because the DLL is missing, but I want to make sure I have the right 64-bit version of isdone.dll just in case.
