You da Man, Erland!
Here's how Windows 7 users can make i1Share useable:
You basically need to replace the old version of EyeOne.dll in your i1Share directory with the same named dll that is part of the i1Match installation.
You may already have that dll on your system it's worth a search before you download i1Match which will install an annoying startup nag window that can be removed with msconfig. It doesn't seem to mess up Spectraview, fortunately.
The version that works for me is:
EyeOne.dll 7/3/2007 10:52am
Just replace the older one in the i1Share directory, found at:
Program Files (x86)/GretagMacbeth/i1/i1Share
Ooh, L = 5.6 on that deep Silver Rag shadow. Can hardly wait to see what happens when I hit it Premier Print Shield.
EDIT: works with Win 7 64 bit, have not and will not test 32 bit.
