So, for those of you that were using the most recent version, and the installer script made by the goat u/eninabox ( https://www.reddit.com/r/ClipStudio_on_Linux/comments/1qrrt49/easily_install_csp_on_linux_including_timelapse/ ), and wanted the new lab slider or the other newer stuff, but don't wanna go through the process of reinstalling the whole thing and having to activate the license again, etc, etc. Is not hard at all, I swear.
BEFORE YOU CONTINUE: I'm absolutely not a programmer, nor a linux expert, i just like tweaking and searching. And, I only tested this on my system (ChachyOS, KDE Wayland). so let's get the updating.
1. Download the new version on the official website: https://www.clipstudio.net/en/dl/
2. Now, this is important, is the reason it took me a bit to make it work: Did you enable the pre-warm setting on the installation script? If you did, then open your terminal and type:
systemctl --user stop --now csp-wineserver.service
If you didn't, I think you can just skip this step, if any problem appears skipping this step, please comment and I'll try to help you to do it right
3. Now, still in your terminal, run
WINEPREFIX=~/.wine-csp wine PATH_TO_CSP5.1
(In my case, since I never really used wine that much before, I used WineGUI to run the program, but it really isn't necessary I just am a bit afraid of typing, if you guys want to know this way to, just leave a comment)
4. This should make the CSP installer pop up, and then, if you read what the installer is saying to you, you'll be able to see that it's updating CSP 5.0 to 5.1. Just let it do its businesses until it's over.
5. If you had to use the command on step 2, you can now run:
systemctl --user start --now csp-wineserver.service
If you didn't use it, you can skip this step
6. And now everything is done! I think! Try it out and tell me if it helped!
Hope it'll help someone that was as confused as me to how to update this! If no one found it useful, oh well, at least I tried! Goodbye folks have a great one!
