Unsupported OS error installing CS5.5 on Windows 10?

[rerobb124]

Error during installation. I chose to install as trial and put in product code later.

First, that software is old enough that it may not work at all with Windows 10... but

An idea that MAY work to install and/or run old programs in Windows 10

-right click the program icon (or setup.exe to install) and select a compatibility mode

Thank you. It's called 'Troubleshoot compatibility' in Windows 10. It used Windows 7 settings for Set-Up and it ran correctly. Yet to determine if the individual programs will require a compatibility setting.

Thanks John, I tried that and it worked for about an hour then everything seemed to revert back to barely functional.

As you mentioned in your reply #2 - did you set each program to run in compatibility mode?

If that doesn't work, I don't know how to get a 4 year old program to work with Win10
