Can I run Adobe Reader and Adobe Standard simultaneously? They appear to be as one.

In a past version of windows and Adobe products Adobe standard did not hand opening two documents simutaneously very well. To work around the issue I loaded reader with a red icon and standard with a white icon. That way when I was using Adobe Standard, and needed to reference another document, I would Open As  "Adobe Reader". Now I am running Windows 11 and purchased Adobe Standard, and then loaded free Adobe Reader to accomplish the same goals. However, once I loaded Standard and then Reader, there appears to be only one program. It appears to be only Standard. If I try to open an additional pdf, and try to Open With, I cannot find an Adobe Reader icon. Can anyone shed light on what is happening? Thx -art-
