I am trying to install The Sims 4 on wine (using 'wine setup.exe' and wine3.12) - and having some silly issues. Here is the error I receive at 0.1% of the install:

So I spent probably 4 hours today troubleshooting as to why whenever I launched the Setup.exe, it would just get stuck on the splash screen, and nothing would happen. Unarc.dll file is dynamic link library for Windows. It is an essential component, which ensures that Windows programs operate properly. Thus, if the unarc.dll file is missing, it may negatively affect the work of the associated software. There is another case when a failure occurs with the message 'Unarc.dll returned error code 12'. This may be due to the too small size of the paging file or its disabling in the system. It is clear that you need to turn it on and adjust the size.

After finding that this error is caused by insufficient space for decompression I tried moving the install location around to different locations - every time getting the same error! I have about 700GB of free space on my laptop, and the game is only 17GB so I feel like there may be another issue.
Error code 12 valorant

Another thing to note: I have installed this same exact file on other windows machines without issue so I know the source itself is okay!
Any ideas? Thank you so much in advance!!
