Windows 10: CMD program.exe "ERROR: %1 is not a valid Win32 application."

Hello everybody.


I was going to format my desktop but I think to get a help Microsoft before.


Some programs don't are executed by CMD and it bring fails in many operations of windows Win.Update/BKP/RECOVER /basic tasks/scripts and others.... These operations fails not shows the message but I know that it's the problem because Windows need to use CMD to conclude several operations in background.


The message "ERROR: %1 is not a valid Win32 application." appears in simple commands in .BAT and .CMD as:

...> tasklist
result: "ERROR: %1 is not a valid Win32 application."


...> taskkill
result: "ERROR: %1 is not a valid Win32 application."


Solution test:

1 - I've tried to clean and fix all that is possible in the "Windows Environment"... nothing
2 - I've tried to delete or change some keys in the REGEDIT... nothing
Many keys as Computer\HKEY_CLASSES_ROOT\batfile\shell\open\command
Many keys as Computer\HKEY_CLASSES_ROOT\cmdfile\shell\open\command
Many keys as Computer\HKEY_CLASSES_ROOT\exefile\shell\open\command
end as the value: "%1" %*

3 - CMD as administrator SFC /scannow inside the system... nothing
4 - CMD as administrator SFC /scannow Pendrive bootable last Windows download available... nothing



Anyone take this error and get the solution?

x is not a valid Win32 Application

I'd like to understand why Win XP reports something is not a valid Win32 application.

Relevance to W10 - the application is built on W10 using VS2017. I thought I had taken appropriate care to not use APIs that aren't available in Win XP. But when it's installed on Win XP SP3 windows gives me a nastygram saying it's not a valid Win32 application.

So what steps should I follow to determine why this is happening?

I came here 'cos I believe that there are people here who know this stuff.

Thanks
