AutoCAD LT 2009 XP compatibility mode not listed

I need to run AutoCAD LT 2009 under Windows 7 (Professional x64), which AutoCAD says works for most general work. To do this you need to run AutoCAD in XP Compatibility Mode.

However when I try and activate Compatibility for AutoCAD I only get 5 options, with any other program I get the full list as the attached file demonstrates. Any ideas?

this is a known "problem" with AutoCAD LT, your best bet is to set it to Vista Service Pack 2 and see if you experience any problems using the program

Also make sure to install any and all updates to AutoCAD LT 2009 as can be found here:

Will do.

However when I try and install the updates I get an Installation Error stating

The service pack could not be installed because the expected Autodesk
product could not be located on your computer.
Make sure that you ar using the correct serice pack for the product.

AutoDesk lives in "C:\Program Files\AutoCAD LT 2009\acadlt.exe"

Out of curiosity if I install an AutoDesk Update 3 will include all previous udates?

the AutoCAD LT Service Pack 3 includes the updates from services 1 and 2.

Based on the folder location of your AutoCAD 2009 you should be using the 64bit version of the service pack, if this is the 32bit version of the program it should have been installed in the "Program Files(x86)" folder instead.

I tried both on Update 1 and got errors.
Running the 64bit version on Update 3 it says I am completely up to date? :-)

I'll try running as Vista SP 2. I presume I don't have to set it as "Administrator".

Very many thanks, Ed

once you run the program try the keyin command: ABOUT
In the 'About AutoCAD' window click the 'Product Information' button on the top right
In the 'Product Information' window it will list the service pack installed under the heading of 'Product service pack' there it should tell you if service pack 3 is in fact already installed

as for the administrator option, I always check the box to make sure that the program has the highest privileges that it would need. I'm not 100% sure if this is really necessary but is a good idea to keep from getting access errors with AutoCAD
