@GruntThe problem I'm facing with rum is anytime I try to open a windows executable, either an affinity setup or dotnet48 from Microsoft I only get a black screen, I can't install dotnet though Winetricks (exit status 5 - user selected 'Cancel') or use the executable from Microsoft Black Screen.
Edit 1 : But with Bottles, the only things I can't do is save my project-file and view online profile.

@Gruntok so I found some guide online here and used it to install affinity inside bottles after many years of no success, and then when I thought everything was fine because the programs started normally (except when it tried to load my online profile) and I could do my work and export it to other formats, but what I couldn't do it open my online account/profile page or save the project as afphoto/design/pub.
So the suggestions I got was to use something called rum, and rum is a script that uses custom wine binaries to run windows executable, what I had to do is to get this wine-fork that was modified for running affinity programs and use it instead, but the problem I face with rum and this custom wine is that I can't even install dotnet48 and that's that.
But with bottles, I can do everything except save my files.
So by far what I've seen in the custom-wine docs is that it says that bottles will not install dotnwt48 properly because it will be missing many reg keys (which I have no proof of, and I don't know how many or what are the keys that's missing)
So my final step would be to find and manually enter the missing keys for bottles, or to make the Winetricks install the dotnet48 properly for rum.
Edit 1 : For additional context, this is my system specs:
---------------------

GPU: AMD ATI Radeon RX 470/480/570/570X/580/580X/590

So I just have to add in the missing registry keys manually, or I have to find why rum won't even install dotnet48 and then install it and then try out affinity.
Ok if any knows what are the missing keys do let me know.

@Wanesty Thanks for the tip, but the guide doesn't seem to work for me, the entire guide seems to suggest that rum is better than bottles and to use rum with the wine-fork but, I first started getting trouble while trying to install dotnet48 and after that nothing seems to work.
For now, I'm just going to try to make bottles work, because I could get past the setup and even start and make projects with it and even export it to other formats, all I need to do is to find out why I can't save files to a directory as afphoto/design/pub.
Or I'm going to have to ask Affinity for alternative payment methods because I just got the money to get V2 but all of my payments are not accepted by Affinity for now, and I need to do this before the Black-Friday offer ends.

OMG I've been waiting for this for 6 years, now the affinity suit is running well in my Manjaro.
But I still need to enable hardware acceleration, but Affinity says "Unsupported Machine Configuration : Acceleration requires Windows 10.0.19042 (May 2020) and your current version is Microsoft Windows 10 Pro (version 10.0.18363)".
I know, a hack'ish way to change the windows build number/version using regedit, but I'd also like to know if I'm somehow using outdated configuration.
Thank you.
EDIT 1 - after some poking around, I just found out that I can't save any work as mentioned in this thread well, so that means I'm back to square one.
