Okay, 
I just installed WLP5.3 last Friday and it worked until it did major crash last night. Since then, anytime I try to open or create a new strategy it gave me an error. (I didn't get the error... sry)
Figuring something got corrupt, I uninstalled WLP5.3 and attempted to reinstall, however, when it starts to perform the install (after accepting the agreement & complete installation prompts) get a message saying 
QUOTE:
"The system administrator has set policies to prevent this installation"
.  Windows ACL doesn't prompt for installation.
It installed on Friday without any issues.  I am the administrator on my personal laptop. I have not installed another other applications or updates.  I rebooted and turned off virus scanner and I still can't get it to install.....?????
HELP!  :)  Any Ideas?By the way, I get absolutely no results whats-so-ever when I do a content search on the forum.  Is it search function working?
