LD Assistant PL System Requirements
Before you begin installing LD Assistant PL on a stand-alone computer, make sure that your computer meets the minimum recommended requirements. See the following table for hardware and software requirements.

** Win 7 and VISTA:
For LD Content to work you will need to turn off the User Account Control

**AutoCAD Plug-in LD Assistant PL is a 32 bit program and requires that AutoCAD be running under a 32 bit OS. LD Assistant PL does not support 64 Bit AutoCAD.

LD Assistant PL13 requires AutoCAD 2013!

LD Assistant Ac 2013 is a 32 bit program requiring XP 32 with Service Pack 3, Win 7 32 bit, but will install on WIN 7 64 Bit OS and run as a 32 bit program.

** Macintosh: There seem to be issues for a small group of users with Win7 in Parallels, check the MAC and Microsoft blogs and user forums for more on the topics and suggested fixes.

Vista and XP seem to be immune from the issues.

** Work-around for Macintosh users running Win 7 on Parallel... Right click on the program link (shortcut icon) and go to properties. Then click on compatibility, then help me choose the setting. Click on the program compatibility troubleshooter on the screen that pops open. After going thru the troubleshooter, the program should open and run fine. But once you close the program you will need to re-open it using the troubleshooter.
