Hi @powerautomator3 ,
I am think the main reason may be you have already have Power automate desktop installed with 0365 license or Microsoft store and again you are trying to install it with MSI installer,this is causing conflit.
Try to remove that software that you have downloaded from MSI Installer and its related files from cache and all.Then try to launch with already existing file.
Also try these below steps.
1. Check Network Connectivity:
Ensure your computer has a stable internet connection. A poor connection can cause login delays or timeouts.
If you're behind a firewall or proxy, verify that it's not blocking communication with Microsoft's authentication servers.
2. Clear PAD Cache:
A cluttered cache can sometimes cause login issues. Try clearing PAD's cache to see if it helps:
The exact steps might vary depending on your PAD version, but it usually involves accessing settings or preferences and finding a "Clear Cache" option.
3. Reinstall PAD:
If clearing the cache doesn't work, consider reinstalling PAD. This can fix corrupted files or configurations preventing proper login.
Make sure to back up your flows before reinstalling!
4. Check for Conflicting Software:
In rare cases, other software might interfere with PAD's login process. Try temporarily disabling any recently installed programs or antivirus software to see if it resolves the issue
(Note:- if you got your solution you can mark as solution and gives kudos)
Thanks & Regards
