Windows 10: Unarc.dll Error. Unable to write data to disk

I had previously installed GTA V on my laptop and it worked smoothly. But I wanted to play again to I tried to install it again but there were some errors that appeared previously as well but I fixed them. I don’t remember how I did it. So its a repack of game and when I am installing it, it shows that unarc.dll returned a code 11. I have required space for game. And I had installed previously the same way in the same storage. But I can’t seem to resolve the issue now. Please help.

Isdone. Dll and Unarc. Dll

Hello

I built a PC like an year ago and it was working fine .

One day I was installing a game and I got an error of archive corrupted i.e Unarc. Dll and Isdone. Dll

After that I installed another game and it was installed successfully.

Then I installed a game and the same error happened

I tried everything

Increasing Virtual Memory worked for me for some time but after a couple of days same error happened again

I tried to copy paste the following dll files and it didn't work for me either.

I tried sfc in CMD

I even reinstalled windows and it still wasn't resolved

It only happens when installing big games like GTA 5

Star Wars Battlefront 2 etc

I used Windows Memory Diagnostic Tool find and error in my RAM and there was No error in my RAM.

My previous Operating System was Win 10 and the same error happened but when I updated to Win 11 I thought that the error will be fixed, but it wasn't.

Please someone suggest me a legit solution

How To Format A Write Protected Flash Memory ?

¿You already tried this one?...

Run CMD


1. diskpart
2. list disk

Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

2. select disk #
3. clean
4. create partition primary
5. select partition 1
6. active
7. format fs=fat32
8. assign
9. exit

with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

good luck!
