Roblox Studio hangs on Wine due to unimplemented VirtualProtectFromApp func

though I know this is more like of a Wine issue that this func is not implemented on their side, but I have no idea how to report it on their helpdesk/forum. so I am asking you to fix this on your side guys.

I think the title tells you everything already.

I suggest you make a detection if the current env is Wine, and stop using the unimplemented “VirtualProtectFromApp” func, and fallback to the standart VirtualProtect instead.

logs from wine if needed:
fsync: up and running.

This happens both in RobloxStudioInstaller.exe and in RobloxStudioBeta.exe.

Expected behavior

To install Roblox Studio normally without any issues under Wine.

I don’t think Roblox cares about Wine support, but at this point just use Vinegar or if you don’t want to do that for any reason, get Studio version version-c98e1b5b4dd94b96, it doesn’t use that function

you are being off-topic, not relevant to this bug report at all.

what if they do? you can’t read the minds of people who work at Roblox.

I don’t like Vinegar. Why? (Do I really need to explain this?) Because I don’t like GO lang, and also I don’t like GTK (bloat). This is the most red flags to me, not including small things like detecting versions that you put yourself into the folder. Also, vinegar only allows you to have one wine prefix, and only one studio version installed. It doesn’t allow you to install studio from a custom source (built-in). You have zero customizability (UI, built-in). The list goes on infinitely… I’m making my own Roblox Studio wrapper right now, it would be a lot better.

This is a “temporary workaround”. Soon enough you won’t be able to use this version without patching studio yourself to not get updates, and then what would you do? the best solution from this is to just get a little support from the Roblox team.

This bug was already reported here. This shouldn’t be something Roblox fixes as it is an issue caused by Wine (and running studio under wine isn’t supported for obvious reasons).

To my knowledge and some testing, I don’t believe there is a Wine and Proton fork which implements the function as of now.
As Stan said, it has already been reported to the WineHQ which has gotten some attention, it will probably get looked into and sorted within the next few months, unless a Wine fork does it first as a temporary fix.

I’m unsure if posting a bug report here will draw any attention from engineering team as this is a Wine-related issue which is out of control of Roblox, the only thing they could do is to not use the function, but considering it’s been in the Windows API since 2022 and Windows 7, 8/8.1 support is no longer a thing, Roblox doesn’t believe there is any issues with using newer API calls.

I suggest you re-read the post again, and stop being off-topic :crazy_face:

Why should Roblox add a detection to fix Wine’s unimplemented issues? Even when implemented, Linux users are still reporting crashing when launching Studio. The best resort is for Wine to fix it, and if they can’t, you can always switch to Windows (there hasn’t been a bug report on a Windows function being unimplemented on Windows🤔)

I just did? I don’t get why I would be re-reading your post and I am also not sure why you are stating that my comments were “off-topic”, please tell me the offending text and I’ll make it clearer for you.

I disagree with the bug report—it misplaces responsibility. This is clearly a Wine issue, not a Roblox one. Expecting Roblox to add specific workarounds for unofficial, unsupported environments like Wine is unreasonable, especially when the function in question (VirtualProtectFromApp) is part of the standard Windows API and has been for years. If Wine doesn’t support it, that’s something for the Wine developers to fix, and it already seems to be on their radar. Posting this as a Roblox bug report just clutters the tracker with issues outside Roblox’s control and sets a bad precedent for expecting official support on platforms that Roblox doesn’t target.

You’re embarassing yourself :pray: relax

Hey everyone, just closing the loop, not a Roblox issue. Thx for the report!
