IDEA- Force Adminstrator Mode, even if Logged in as Admin

[catbait]

Even when I log in as an Adminstrator in Vista, there are several programs that will not install because they say I need Administrator Priviledges.  I have no clue how to fix this and would appreciate it if there was a code to disable whatever is lurking in the Register to prevent these actions.  2 programs in particular are A Lexmark driver, that shows up as an unknown device in DevMgr, and another is a PDF to Doc convertor program that I can not install.

For both the driver and the tool: Get updates to be Vista compatible, if none are available, switch to similar tools that are Vista compatible.

Most trouble caused by Vista is incompatible drivers.
Most trouble using/crashing Vista is caused by incompatible drivers.

What you might want to turn off is UAC (User Account Control) but then you most probably will get bitten by both statements I posted above.
