We would recommend you to update your OS till the latest actual version. According to Microsoft, it should help with the 0xe0434352 error. This regular error arises after unsuccessful OS update.
Same problem over here. I downloaded the latest version from the site. Installs just fine. However, nothing happens when I open the app.
Downloaded the latest alpha version. Nothing happened the first time I ran it. After that it does show the loading visual but it still doesn’t do anything.
Finally, I tried disabling my antivirus, but that did not help.
Any ideas?
Hello, Milan! Let’s try to figure it out!
First of all, I need to ask you about your OS. Which build of Windows are you using? Would be cool if you could take a screenshot of your Windows About page
Start>Settings>System>About>Windows specifications
Are you using the latest GPU drivers?
Is everything okay with system rights? Have you tried to open the installer as an administrator?
Hi Artem!
Yes, I’ve tried running both the installer and the app as an admin. It did’n change anything. My GPU is up to date,
Here’s the About page. I might have worse problems than just opening Lunacy 
as having no processor is a bit weird, gotta admit.
Heyo!
Hmmm…Are you using the latest version of .net framework & visual c++?
If this will not help I will advise updating your OS to the latest version.
BTW
Could you tell me which CPU and GPU are you using?
Yes, .net and c++ are up-to-date as well as the OS.
It’s an i3 5005U and a Radeon R7 M360.
Your OS is not up-to-date. 1803 build is Apr. 2018. Actual version is 1903. We can reproduce your environment only if you update your OS.
Hello. Not sure I am seeing the same error but here is Lumacy’s log file content:

Since neither the store not the direct download app were running, I downloaded alpha 4.0.0.1 and have been trying to launch the x64 version (x32 also fails)
I should add that I am running Windows 10 Pro Version 1903, build 18362.418.
Update
Installed the latest updated vc_redist.x64.exe and now is working.
Having the same issue, first tried from the windows store, tried to launch it multiple times, tried to launch as admin, nothing.
Next downloaded the windows installer, same thing, it doesn’t launch at all.

Thank you a lot for helping us to make Lunacy better!
We were able to locate the problem with the help of the logs you’ve sent us.
The next version should be working fine on your PC, but if you experience any issues with that, please let us know about it in this thread.
The planned release of the next version of the App will happen in a couple of weeks.
May I ask you for your OS and Lunacy versions, please? Thanks 
I LOVE Lunacy and I am so grateful for all the improvements you have made to it recently. BUT…
I am now also having the same problem.
I can open Lunacy, but then nothing happens.
None of my old files will open properly either. I have tried uninstalling and re-installing the app multiple times. Each time I do, it starts off looking like it will work, but when I try to open a previous file that I need to work on, it just stops working - and then when I try opening the app again after that, it is back to not working at all again.
So I have the latest version (I have now downloaded it again 3 or 4 times!), and I am working on Windows 11 Pro.
It was working fine the last time I used it (about a month ago) - it just started giving this problem when I tried using it yesterday.
Can you, please, specify whether you have this issue with local or cloud documents? How old are your files? It would be great if you could share one of them in the DMs
I am so sorry for not replying earlier - the email went to my spam, so I didn’t know you had responded.
But I am excited to say that I just tried Lunacy again now and it’s working! So something must have been fixed - Thank you!
