I have tried using 4G from my phone but this did not solve any problem on my side.
I have also managed to install Roblox by opening the installing various times until it launched, but now I am experiencing crashes every 20 minutes or so, does anyone have such problems after having troubles installing it?
Launching studio using Roblox studio mod manager fixes this for me, using the default installer does not work
Following @gillern’s post, I have found a workaround which is using Bloxstrap. It is likewise an alternative to installing Roblox Player
Please never run the installer with administrative permissions, it can make it worse if it does successfully install.
It is because it is it’s own bootstrapper, meaning it mimics what the Roblox installer does. 
When trying to install the Roblox Studio update, it just does not install. After it’s done, nothing happens. I reopen and it installs again. I restart computer and nothing.
I didn’t say to use cellular. Connect to something without cellular. Cellular data blocks Roblox for some reason.
I have never had any problem with using Roblox and cellular data, indeed most of the time it would fix issues I had with regular house connections: ability to buy items, friends statuses, website images loading and so on. In my case, cellular is not a problem, but this might depend on which ISP service you are using and the country you are in (though I could be totally wrong)
For me, it stops, then eventually goes straight to 100% and closes without the install actually happening. No indication of it failing or anything. This happened both with the newest update as well as Roblox entirely when I tried reinstalling all of it since I couldn’t get it to update.
After some recent update this is happening to me, I’ve deleted all roblox files, restarted my PC, tried reinstalling from scratch and it will still crash before fully installing without any warning every time I try to install it. I use a mobile hotspot as internet, connecting to a different network is not an option for me
I’ve had this issue before on a computer that had seen long periods of inactivity.
Both Studio and Player would not want to upgrade/install at all on the machine, and the internet I had been using was weak and sourced from my phone’s data, which further made this frustrating with every attempt to troubleshoot.
The only way I was able to fix it was by uninstalling any existing version of Roblox Player or Studio, removing every Roblox related registry entry, restarting the machine and then reinstalling.
I do want to note that tampering with Registry Editor could cause some unwanted problems, so do this at your own risk!
To do this, run ‘regedit’ or search for Registry Editor, then in the editor press CTRL+F and search for ‘roblox’ (case insensitive). Ignore the .rbxl and .rbxlx registries, as these correlate to file types and should not interfere with the install. To delete an entry, press Delete while the entry is highlighted. Once that is done, restart your computer and install Roblox as usual.
I’ve found the solution to this, what you have to do is go to the shortcut in your desktop, open file location and open the RobloxPlayerLauncher, not the Player, which is this one:
If you don’t have a shortcut in your desktop for whatever reason, you just gotta search in this directory on your PC, which you can search by opening windows explorer and just clicking on the folder directory at the top, which should look something like this
But after you click, you can put a directory. Copy this directory (with your user replacing the red part)
And then find the latest version which you can check by seeing the last modified date of the folders in there by checking their properties, which you should then find the RobloxPlayerLauncher inside.
Hope this helps while they fix this bug.
I can confirm this is happening far too much lately, I’ve barely been able to join a game once without roblox “deleting” itself afterwards.
To anyone not being able to find roblox versions in the localappdata folder look inside here instead:
Roblox instead of installing into… appdata like before it’s now here…
The fix by the way is run “RobloxPlayerLauncher.exe” inside of that folder, NOT playerinstaller, playerLAUNCHER only, that should fix it for you.
Also if it helps the developers this is what the installer creates in C/ProgramFiles(x86)/Roblox/Versions after this installer is ran
Prior to using this method aka, using the installer downloaded from roblox these files aren’t created anywhere and the real installer just closes instead, “RobloxPlayerLauncher” seems to install roblox better than the “RobloxPlayerInstaller” 
Is there a way to download roblox studio like this?
This is still occurring. Unable to install studio at all. Also unable to fully delete studio from computer
possibly any updates? this is a veryy high priority issue, not being able to install the game or studio means you can’t play roblox at all or develop at all… how is this taking a month?

This has happened since my client closed with “Roblox needs to update we’re sorry” or something like that.
Both my client and studio are broken.
I have uninstalled the client, uninstalled the studio, fully removed all the folders in appdata, I have removed all registry entries related to Roblox and still it will not update nor install when running either of the two client or studio installers.
I can provide a DMP if needed.
It has stopped crashing as much, but its still horribly slow to download.
This is not because of my internet speed, I can download other apps relatively fast.
This just takes way more than it should.
This issue still persists. From today’s Roblox update it seems that even when force running both RobloxPlayerInstaller.exe and RobloxPlayerLauncher.exe in administrator mode, the installation still gets stuck and eventually crashes.
My roblox studio crashed with reason “no verified patch could be loaded”, none of my work saved.
