good morning,
I'm trying to install some very compressed game packages using different PCs (for example: Ace Combat 7 Skies Unknown v1.0.1 (Monkey Repack) [FitGirl Repack] and RESIDENT EVIL 2 Deluxe Edition + 9 DLCs [FitGirl Repack]).
If I use the sandboxie, a very common error appears regarding two isdone.dll and unarc.dll libraries that promptly disappears by installing the package outside the sandbox.
thank you
I've been trying to make an installer by Inno Setup which only supports zip/bzip/lzma/lzma2 compression methods. I packed my archive by FreeArc (output file extension is .arc but renamed it to .bin) but Inno Setup is not able to extract it. I searched on internet how to implant arc decompression into Inno Setup but all sites refer to FreeArc official website which is dead for a while.All I need is the code to use the necessary dll files to give Inno Setup the ability to decompress arc archives plus the list of those dll files needed to do so.I appreciate any help.
This answer has been superseded by How to decompress archive file with progress and cancel button in Inno Setup using unarc that uses unarc.dll instead of driving the console Arc.exe.
For CreateCallback function, you need Inno Setup 6. If you are stuck with Inno Setup 5, you can use WrapCallback function from InnoTools InnoCallback library (and you need Unicode version of Inno Setup 5).
So I've been having an error with my pc, isdone.dll and unarc.dll error. I say "an" because it is all just one message. At first i thought it'll just happen when i installed games, they'll fail and give the error message mentioned above. I've done everything on YouTube, from allocating ram, re-downloading the missing files, deleting temp files. You name it, i probably did it. But the error persist. I wouldn't mind too much if it only affects games, but even programs for coding, they'll fail as well. I'd really appreciate any resolution please help me
Don't know what you bought?
The main one, size of the hard disk or ssd, or both!
available space !
Amount of memory installed
You have the different possible configurations in the given link
Okay, this issue started when it was still windows 10, hence i thought the update might repair this issue. My ssd is 255gb and my external hdd is 1tb. I previously had 8gb ram but then installed an additional 4gb but says total is 10gb ram instead of 12gb which is fine, the drivers must be using up the other 2gb... Long story short, it's an AMD Ryzen 5 3500U with radeon vega mobile gfx. But in terms of configurations, I'm not sure what that entails, maybe we using different jargon for the same thing and we are lost in translation.
I have 1tb of free space in my external hard drive, and i have 110 gb free space in the internal ssd. Usually it would be programs or games over 20gb that produce this error. In fact, just last night i tried unreal engine, unity and nfs heat and all 3 gave the same error, but 2 nights back i successfully installed web expression, and euro trucks. I test both programs and games because I'm trying to narrow down the issue, like the space or system requirements that do not produce this error and as far as i can tell, it's just the space, not ram or vram or processors that cause this, just the fact that installing anything over 20gb would cause this error
110 gb of free this can be a cause, although it seems to me enough for most of the time
so try to free up as much space as possible
move personal files, delete unused programs etc!
Are the games from known platforms?
I ask because I have read several times that this happens with games from certain sites!
Previously i installed AC 4 black flag and it worked, along with nba 2k16. But then i started having this isdone.dll error and both of those stopped working so i had to reinstall them, that's when i found out about this error. So i know it's not the space, cause I've even tried installing on my external drive but still the same issues. But i just tried to re-register that isdone.dll in command prompt and I'll type verbatim what it's showing me now...
To my knowledge, when i search for the isdone.dll i can find it on appdata on my C drive... But now it's saying it's not registered. I don't want to sound like i know what I'm doing, cause honestly i wouldn't even know about this had i not be speaking to you, and although the issue is not fixed, it's a relief that you take your time to help me out, but this does mean that space is not the issue

Unarc.dll returned error code-6, then something about social club pops up, and rockstar installer turns itself down. I have tried reseating my ram, chkdsk, anti malware, run it as administrator, move rockstar installer, change the installation directory but nothing helps. I have read that it might be due to hdd bad sectors? With far cry 4, I insert the CD disc, launch setup, and about 2% I get unarc.dll error code-7.
You've got a corrupt library on your PC, in this case the unarc dll. It's used by the installer to uncompress and install the game files. It might not actually be corrupt, just a newer version than the installer expects.
I'd try locating the file on the PC, renaming it to unarc.dll.old, reboot the PC and then try and install the game. My guess is that the game will install the library again from the install CD as part of the installation.
