I created a few programs using gfortran in Windows 10 Pro, where they work well, but when I transferred the .exe files to my W10 Home laptop they all failed to start. I've tried a few ideas, such as compatibility with earlier Windows versions, but no success.

When I tried to run one of my programs (Chat.exe) the following message appeaared:

Chat.exe - Application Error
The application was unable to start correctly (0xc000007b).
Click OK to close the application.

I had no option but to comply!

I opened the Event Viewer (I had to Google how to do it) but I didn't understand what I saw. However, I right-clicked the most recent entry in the list and found the following information:

The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{C2F03A33-21F5-47FA-B4BB-156362A2F239} and APPID{316CDED5-E4AE-4B15-9113-7055D84DCC97} to the user DESKTOP-71CBE0F\alant SID (S-1-5-21-3699571922-1049258911-776565558-1001) from address LocalHost (Using LRPC) running in the application container Microsoft.Windows.ShellExperienceHost_10.0.19041.423_neutral_neutral_cw5n1h2txyewy SID (S-1-15-2-155514346-2573954481-755741238-1654018636-1233331829-3075935687-2861478708). This security permission can be modified using the Component Services administrative tool.

From this I think it is telling me that some aspect of my devcelopment machine is set to a value that makes it incompatible with my laptop, but maybe someone will tell me otherwise. If anyone needs more information, please give me detailed instructions as I am not too familiar with the inner workings of Windows.

The message mentions the Component Services administrative tool. How do I access that and how should I use it? Would I need to use it on my development machine or the laptop?

I'd appreciate whatever help someone could give me.
 
Are both machines the same architecture - both 32 or 64 bit.

Does it use any DLLs? On your source machine, pop up a cmd prompt and unset the path

set path=

Then run your program - does it work?
If it doesn't work, pop up another cmd prompt and see what is on your path - is it pointing to any gnu libraries.
