New computer, Windows 10 version 20H2, PWP 8.0.231
tif files created by PWP 8 and saved on old computer using Adobe RGB (1998) profiles throughout open fine.
Script files for the old tif files that, themselves open just fine, produce the following messages:
"Cannot find assumed color profile:: C:\\Windows\system 32\spool\drivers\color\Adobe RGB.icm Note, extension is icm and lack of "(1998)"
Analogous messages for camera and working space profiles.

System settings:
Display Color Profile Adobe RGB (1998).

PWP settings:
Color Management: Enabled
RGB Working Color Space--Adobe RGB (1998) Note presence of "(1998)"
Assumed file Profile and RGB Camera Profile also Adobe RGB (1998)
On Startup Set Monitor Profile from System Settings

Relevant contents of C:\\Windows\system 32\spool\drivers\color\
AdobeRGB.icc Note, extension is icc and not icm and "(1998)" is absent

Presumably, what happened was that on the old computer you had a copy of Adobe RGB.icm which you then selected as your assumed color profile. This could have come from any number of other applications that install profiles when you install the application. There are a lot of different and presumably equivalent versions of Adobe RGB out there. If you still have access to your old computer, you should be able to find the missing profile there. Note that the filename of the profile and its internal description which is used to select profiles from lists are not necessarily the same so the absence of 1998 is not necessarily significant.

If you can't locate the old profile, just copy the Adobe RGB icc file and rename it.

That seems to have fixed it. Thank you.
