When I go to reopen PE Builder to update the software it says that I need to have administrative privaledges. I am the administrator for this PC.
I have Windows 7 Pro and I am on a home network domain. I am an administrator of both the client PC and server PC. How can I access PE Builders again.

"It" isn't PE Builder, it's more likely your security settings and/or apps. I run PE Builder on Win 7 no problem.

On Vista and Windows 7 computers, administrators do not run in admin mode by default for security reasons... You must right click on the program and select "Run as Administrator"

thanks to info
