How do I start Photoshop CS6 without Run As Administrator

Question

I was encouraged to post this here (updated from post to the Photoshop forum)
I've seen several similar threads with problems with Bridge ()for beta CS6), nothing recent with run issues with Photoshop CS6
I have installed most of the programs downloaded from the Cloud. Most run. So far, from my user account I've found Bridge, Encore and Indesign encounter a "Problem" upon opening and close with no further message or details. Dreamwever, Flash, Illustrator and Premiere run as far as I've tested. Everything seems to start fine from an admin account.
From my user account Photoshoip CS6 brings up a message about a locked scratch file and cannot run. I can start PS CS6 using Run As Admin and everythig seems to run fine. I've tried changing some permissions on discs and on my user account still has PS  CS6 fail to start. (I need to check this again) I've read similar posts on earlier releases. I have tried purging the preferences, both manually and using the crtl+shift+alt start. I still cannot get PS CS6 to run from my user account.
CS5 prograams from Design Premium start/run fine AFAIK
I did not instal the CS6 beta
FWIW
Gigabyte MB, w/ i72600k
Windows7 64bit
SSD for C:
standard disk for user accounts (moved /user to this disc)
standard disks for scratch and file starage (each its own disk)
I tried the uninstall/reinstall game without any change.
I'm out of ideas.

Actually the problem is not unique to Photoshop CS6-64:
In PS6, I can launch it (after I launched as Admin and set cache preference to another drive), but if I try to save a project as PDF, I get this message:
"(X) Could not open a scratch file because the file is locked, you do not have necessary access permissions, or another program is using the file. Use the 'Properties' command in Windows Explorer to unlock the file."
Since the only user choice in PS is in Preferences/Performance, I have no way to know what file and where it may be located. But I suspect the issue is outside of PS, perhaps in Acrobat?
I also cannot launch Encore for what appears to be the same reason (locked cache/scratch file), so the issue goes beyond PS.
One thing that seems a common thread is that these issues seem to affect only users with SSD C: drives using Win7.
Can't someone at Adobe chase down these issues that are affecting so many of us. At the very least, tell us the locations of the locked files and a method of unlocking them. I have tried giving blanket permissions to as many likely folders as I can find, and not only does the problem persist, but I am worried about my system security.
Please help. Please?
