And if I open the link I get version 7 which I already have installed.
Is there a solution to avoid this warning?
Thank you

If you start cmd.exe , type powershell.exe -noprofile . Does the error still occur?
yes, i get the same result..
And when you logon to the same computer with another account?
Any update?
Sorry for the delay, unfortunately I don't have another account..
but yesterday i uninstalled powershell 7 and terminal, i reinstalled only powershell 7, but if i run powershell.exe -noprofile it still gives me error...
Ok.. Just to clarify things for me:

- Powershell 5.1 (powershell.exe) doesn't start at all? Or it does and in background the error is logged?
- Powershell 7 (Which you can start from a command-line as pwsh.exe) does work?
Although I have not installed version 5.1 in the apps, running the powershell.exe command it starts, but with error id 300.
while version 7 boots normally without errors.

5.1 is included/is part of the Windows OS, it gives an error, and you can't do anything or? Powershell_ise.exe does work?

Personally I don't use 5 that much anymore, 7 is the future . Reinstalling your system isn't an option?
Patience... Powershell_ise.exe is not installed
I'll think about reinstalling!
Thank you
