I use the features of Acrobat Pro 9 infrequently but read PDFs all the time. Should I install Reader X and make it my default reader? Seems that would reduce memory and cpu usage.
I experimented with Reader X's install package. I let it run to the point of starting to copy files before I cancelled. It gave me no warning about my having Pro 9 installed.
Running Windows 7 Ultimate.
The only supported combination of Reader and Acrobat is Reader X and Acrobat X.
That being said, it may work but then again, it may cause some unpredictable issues.
I have read for years that Adobe does not reccomend (and I think that it doesn't even support) having Acrobat and Reader installed on the same Windows machine, but have never heard of a warning when installing either with the other already there...
