I had a similar issue, but it is not the Everquest2.exe that was not found, it is the eq2.exe. I see some others have also pointed this out. I am using the new streaming client over an old install of EQ2. One that I had run the Vista uninstall on but didn’t delete the directory structure, I then moved Sony directory to the new Win7 PC and started using the new downloader. After moving the new streaming client files to the old \Program Files (x86)\Sony\Everquest II directory I got EQ2 running again with minimal downloads. But the new streaming client does not create/use an eq2.exe file. So, Profit Updater, EQ2Maps Updater, and ACT all had fits. As a work around, I created an empty text file eq2.txt in \Sony\Everquest II, then renamed it eq2.exe and pointed all these programs to and got them working with no issues. I hope this helps.
Also, a friend is having this issue I could not solve. See here,
